Samsung OLED S95D vs Samsung OLED S90D / S94D (WRGB OLED)

Samsung S95D offers excellent HDR performance, delivering consistent effects across all scenes exceeding 1500 nits, except for the fifth, where brightness drops to 800 nits. Despite this, the TV maintains a high level of picture quality. A significant advantage of QD-OLED technology is the ability to maintain high brightness even in the smallest elements on a black background, which is rare in LCD and mini LED TVs. As a result, every scene impresses with strong lighting effects, regardless of the size of the illuminated surface. Only in the brightest scenes with a large light area does brightness drop slightly, which is typical even for standard LG OLEDs. Additionally, the quantum dot coating has allowed for an unprecedented high coverage of the BT.2020 colour palette at 88%.

In the tested film scenes, the Samsung S90D television achieves impressive brightness results, exceeding the 1000 nit barrier in the first four shots, which can be considered a remarkable outcome. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nit, but it still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour space coverage value of 98%, which guarantees extraordinarily rich and realistic colour reproduction, further enhancing the image quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

On the Samsung S95D, the best colour reproduction mode is the Filmmaker mode. We conduct all our tests in this mode. Although initially, the image in this mode may seem a bit warmer to the viewer, it provides significantly more detail compared to the standard or dynamic modes, which are always oversaturated and artificial. Therefore, Filmmaker is the most closely aligned with the vision of filmmakers and ideal for watching high-quality content. It is worth noting, however, that the factory settings are not perfect, despite dealing with premium segment equipment. The image may contain certain issues that affect the overall quality of the displayed scenes. An example is the drops in red colour in the white balance, both in HD and HDR content. Colour Checker tests showed that the colours lean towards cooler tones. The image is dominated by blue hues, and the overall colour spectrum is distorted. As can be seen in the picture below, the boy from the film appears in cooler tones, making him look less natural. When it comes to brightness characteristics for HD content, it is quite accurate, although there are minor errors. The biggest issue arises when displaying 4K HDR content. The EOTF curve, which seems appropriate at first glance in test patterns, in actual film scenes shows that the TV sometimes "messes around" with the image. This results in some scenes appearing slightly brighter and others darker.

Samsung S95D offers quite decent factory colour reproduction; however, it has some shortcomings that may require calibration to fully utilise the potential of this television. The process is recommended to achieve the most natural and immersive image possible.

The S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem too warm, and users who have switched from Standard mode might experience a slight shock. It’s worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to appear warmer than they should. In practice, this means that certain shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates slight fluctuations, which may result in the image being minimally darker, especially in the shadows. This can affect the clarity of details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is located above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, Samsung S90D delivers a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

How much can the picture quality of a TV change after calibration? After calibration on the Samsung S95D, the white balance has significantly improved, eliminating all major errors, allowing for a more natural and harmonious colour representation. In the case of 4K content, there are only minor imperfections which do not affect the overall picture quality. Thanks to the calibration, viewers can now enjoy more balanced tones, which better reflect the intentions of filmmakers. The contrast has also improved, and the gamma shows even better results. This means that the differences between bright and dark parts of the image have become more pronounced, resulting in better depth and detail of scenes. As a result, shadows have gained more detail, and bright areas are no longer so overwhelming, providing a more realistic visual experience. However, it should be noted that the EOTF curve is slightly below the expected level, which may affect how the TV handles dynamic scenes. Nevertheless, after calibration, the overall picture quality has significantly improved, and viewers can now enjoy a visual experience that is more in line with the creators' intentions. The TV handles subtle tonal transitions and contrast better, making it more suitable for watching movies and high-definition programs. Ultimately, the picture after calibration is closely aligned with reference quality, making the visual experience even more satisfying.

After calibration, the Samsung S90D TV in movie mode looks even better than one might expect. The white balance for both HD and 4K HDR content has been improved almost to perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, leading to a natural reproduction of details, especially in scenes that require a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of a wide colour gamut and does not offer as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

The contrast has also seen a significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between bright and dark areas of the image. The EOTF curve, which showed problems with overexposed scenes before calibration, now demonstrates better results. This effect allows for greater detail to be preserved in the bright parts of the image, especially in HDR materials.

How does the television handle tonal transitions in lower quality materials? Generally speaking, the S95D performs exceptionally well. On the screen with the light bulb, there are virtually no transitions between shades of grey, making it one of the best televisions we have tested in this regard.

When it comes to digital processing, the entirety of the image — from branches to the models' characters — has been well rendered, with no jagged edges or overly visible contours. However, we must point out one issue: the image has been slightly cropped. Nevertheless, the television performs brilliantly, and details in lower quality materials are still noticeable and well-defined.

Television S90D handles tonal transitions very well. Thanks to the technology used, transitions between colours are smoother and more natural. You can also use the noise reduction feature, which further smooths out tonal transitions, which can be useful in certain situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing out of desirable film grain, thereby reducing the cinematic feel of the image. For this reason, caution is advised when using this feature, as it’s better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels in scaling images from lower resolutions. The S90D Samsung TV effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-represented, showing no significant jaggedness that could degrade image quality. With effective scaling, even materials in lower resolution present attractively on the screen, satisfying users who prefer various sources of content such as regular antenna/cable television.
