LG OLED G4 vs Sony A95L

The LG G4 excels in delivering an incredibly vivid HDR experience, positioning it as one of the best models in its class. Equipped with second-generation Micro Lens Array (MLA) technology, it achieves a remarkable peak brightness of 1474 nits in real-world scenes. While it may not match Mini LED-backlit LCD TVs in full-screen white scenes, the overall performance is outstanding. The fine details in HDR content shine brightly, a distinct advantage of OLED technology over non-OLED displays. With this impressive brightness and wide DCI-P3 colour gamut coverage, HDR content is brought to life with unmatched engagement and immersion.

Sony A95L offers an incredible HDR effect, achieving an impressive brightness level of 1500 nits in scenes such as those from Life of Pi or Sicario 2. These results are truly remarkable – the bright elements in these films practically come to life on the screen, providing the viewer with immersive visual experiences. The only thing to note is minor issues with maintaining brightness in the scene from The Meg, where the entire scene is flooded with light. However, this is a natural effect related to OLED technology. The wide coverage of the BT.2020 color palette at 89% is also a significant advantage, placing A95L Sony among the top TVs in terms of color reproduction. All of this is made possible by the QD-OLED panel from Samsung Displays.

Before calibration, the "Filmmaker" mode on the TV had a noticeable red and green colour dominance, resulting in a warm-yellow hue across both SDR and HDR content. This warm tone, typical of modes like "Cinema" and "Filmmaker," led to a yellowish cast that was evident when switching from the "Standard" mode.

Looking at the brightness characteristics, the Gamma chart showed decent performance for mid-tones and bright whites, but it struggled with the darkest details, which tended to merge into a black blob. HDR content, as represented by the EOTF curve chart, displayed a drop in contrast due to excessive brightness, which overshadowed fine details and negatively affected the overall image quality. Additionally, the "ColourChecker" chart revealed that colours were under-saturated, contributing to a less accurate and vibrant visual experience.

This provided a good foundation to build on, but calibration was needed to bring out the full potential of the "Filmmaker" mode and address these issues.

The best factory mode in terms of color reproduction in Sony A95L is IMAX Enhanced. This is a mode that, at first glance, seems to be well calibrated; however, upon closer examination, several areas requiring improvement can be noticed. First and foremost, the white balance for both SDR and 4K HDR content is skewed with excessive blue and red color, leading to a subtle pink tint, particularly noticeable on neutral tones. As a result, skin tones are inaccurate, affecting the realism of the displayed image. This is clearly visible in the comparison photo below. Additionally, the Colour Checker test confirms the presence of these errors—color samples often deviate from their reference values, indicating some inaccuracies in the factory color reproduction of A95L Sony. The maximum deltaE error values reach up to 5.8, which is a clear indication that colors are not always reproduced as precisely as they should be.

Regarding brightness characteristics, the gamma for HD/SDR content is generally quite correct, maintaining an appropriate balance between brightness and contrast. Unfortunately, there is a significant jump at the end of the graph, leading to a strong brightening of the image when the screen is fully flooded with white. This can make scenes with very bright backgrounds, such as snowy landscapes or intense daylight, appear overly vivid and lose detail. In the case of HDR content, the EOTF curve, which is responsible for controlling luminance, is slightly boosted compared to the reference values. This, in turn, causes the image to be somewhat brighter than it should be, which may affect the perception of more subtle details in the darker areas of the frame.

The manufacturer has been offering extensive support for the calibration process in its LG televisions for many years. Therefore, we used 2- and 20-point grayscale adjustments along with an advanced CMS (Colour Management System) to optimise the display. As shown, the calibration procedure greatly improved each parameter. The results included studio-quality colour reproduction, enhanced detail in dark areas, corrected brightness characteristics, and accurate colour saturation. This led to a near-perfect match with the reference image—the one the film director saw on the preview monitor. It’s also worth mentioning that LG G4 televisions are unique in offering even deeper image adjustments through 3D LUT matrices, a feature primarily suited for post-production or graphics studios.

Sony A95L offers excellent tools for professional screen calibration, allowing you to maximize the capabilities of the IMAX Enhanced mode. We used them to bring the image to a level that will satisfy even the most demanding viewers. After calibration, the white balance for both 4K HDR and SDR content looks simply great – almost perfect. The Colour Checker test confirmed that deltaE errors do not exceed a value of "2", which means that color reproduction is extremely accurate, and any deviations are practically imperceptible to the human eye.

Calibration also brought a significant improvement in terms of brightness – gamma is now perfectly balanced, eliminating the previous issue of excessively brightening scenes with very bright backgrounds. As a result, even the most vibrant moments, such as snowy landscapes or intense daytime scenes, appear natural, without the effect of clipping. The EOTF curve, which is responsible for controlling luminance in HDR content, has also been improved – it now reaches a reference level, both in synthetic tests and in practical movie watching.

As a result of the calibration, A95L Sony offers excellent experiences, whether you're watching material from regular television or your favorite movies. Every detail is reproduced exactly as the creators intended – without unnecessary brightening, with perfectly rendered colors and appropriate depth. This shows that this television, after professional tuning, is capable of competing with the best screens on the market, offering an image that truly impresses.

The LG G4 does not perform well with materials rich in tonal transitions, leading to a pronounced posterization effect. However, the manufacturer has included a smoothing system called "Gentle Gradation," with three levels: Low, Medium, and High. These settings are effective at smoothing bright colours, though less so for darker tones. It is recommended to use the Low setting, as the higher levels can distort the director's intentions by removing film grain.

When it comes to upscaling lower-quality material, the television's performance is quite good, delivering a sharp and clear image. However, attention should be paid to the jagged edges of fine details and the occasional halo effect around figures. This occurs due to the sharpening imposed by the LG G4, even when the lowest setting is selected (0). This is a noticeable change from the LG G3, which did not apply such strong sharpening, even at setting 0.

The tonal transition smoothing function in Sony A95L works really well and is worth noting. We recommend setting it to the "Medium" level because at this value, you achieve an ideal compromise – there are no artifacts, and the image looks extremely natural and pleasant to the eye. This allows for smooth transitions between different shades while maintaining scene detail, which further enhances viewing comfort.

As for upscaling, you can see the full power of the XR processor here. Sony A95L handled our test material featuring a model excellently – the image is exceptionally clear, there are no excessive jagged edges, and the details in the background are perfectly preserved. The XR processor effectively improves low resolution, providing very good results that allow you to enjoy content in almost high quality, even if its source is not ideal.

The LG G4 offers a maximum refresh rate of 144 Hz, achievable when connected to a powerful PC. For most users, however, the TV operates at a maximum of 120 Hz, ideal for watching sports or other content with fast motion. To improve image fluidity, the television includes the "TrueMotion" motion smoothing system, which features two separate sliders: De-Blur (for the sharpness of moving images) and De-Judder (for judder reduction). These sliders allow users to adjust the level of smoothing between 0 and 10, ensuring everyone can find the ideal setting.

With a response time of 0.78 ms, the LG G4 delivers exceptionally clear images, outperforming LCD televisions, which can have much slower response times. This results in no trailing blur behind moving objects, as shown in the "UFO Test." The TV also provides precise control over motion smoothing, which is especially beneficial during fast-paced video game sequences. Thanks to OLED technology, the G4 eliminates ghosting, ensuring a crisp and clear image even during the most dynamic sports or action scenes.

Sony A95L is a TV that should satisfy both gamers and movie lovers. When it comes to watching movies, this model is equipped with Motionflow technology, which allows precise adjustment of whether we want the image to be more "framey," like in traditional cinema, or exceptionally smooth, like in cinema TVs. The "Smoothness" slider allows you to regulate the level of smoothness – from subtle changes to a more noticeable effect, while the "Clearness" slider is responsible for reducing flicker and artifacts, helping to achieve more natural and clearer motion. Regarding gaming and watching sports, the A95L Sony television offers a refresh rate of 120 Hz, making every dynamic action look incredibly smooth. Gamers will appreciate the lack of blur, while sports fans will see every movement in full sharpness. Overall, the TV performs great – both with fast-paced gaming and emotionally charged movie sequences.

The LG G4 TV supports all the features encompassed by the HDMI 2.1 standard, making it a gaming powerhouse. During testing, every feature activated seamlessly, ensuring a smooth experience for both console gamers and PC users. Notably, the HGIG mode (HDR Gaming Interest Group) is implemented correctly, allowing games mastered to brightness levels higher than the TV’s maximum luminance to map tones accurately, preserving the game’s original visual integrity.

A notable highlight is the dedicated GameBar, which can be accessed at any time to quickly check or adjust game settings. More importantly, enabling VRR (Variable Refresh Rate) does not compromise contrast—a common issue in TVs with local dimming or Mini LED backlighting. This is thanks to the OLED panel’s self-emissive pixels, which maintain consistent contrast. However, a slight grey flicker may appear when VRR is enabled, though this is standard across OLEDs.

In summary, the LG G4, like most OLED TVs, is ideal for gaming and online competitions. Its HDMI 2.1 ports offer a full 48 Gbps bandwidth, supporting features such as VRR, ALLM (Auto Low Latency Mode), G-Sync, FreeSync, and HDR Dolby Vision gameplay, ensuring an exceptional gaming experience.

Sony A95L is a television that will truly satisfy gamers, thanks to several key features that set it apart from the competition. First of all, a 120 Hz refresh rate – this is something that anyone who loves fast action games, racing, or dynamic shooters will appreciate. This ensures exceptionally smooth visuals, making gameplay more satisfying without annoying stutters. The A95L Sony also has an ALLM (Auto Low Latency Mode) feature that automatically activates low latency mode when we start up a console. What does this mean? Above all, faster on-screen responses, which is invaluable in games where every second counts. Additionally, there’s VRR (Variable Refresh Rate), which adjusts the refresh rate to match the frame rate generated by the console. The result? No tearing, and everything looks smooth and consistent – even with fluctuating FPS.

It’s worth mentioning the support for Dolby Vision with low input lag in games – something we don’t often encounter in televisions, yet it’s included here. This makes the visuals in HDR-enabled games incredibly vibrant, with rich colors and excellent contrast. Both the brightest and the darkest details are visible, making everything look just as the game developers intended. And let’s not forget the "Game Bar" – a small but very practical feature. It gives us quick access to all the important gaming settings, such as VRR and latency information. There’s no need to interrupt gameplay to adjust settings – everything is at hand.

However, it is important to remember that the A95L offers only two HDMI 2.1 ports with full bandwidth, one of which is designated for eARC. This may pose a limitation if we plan to connect multiple devices – for example, a next-gen console and a soundbar simultaneously. In such cases, the eARC occupying one of those ports may be somewhat troublesome, blocking the ability to connect a second console.
