Samsung OLED S95D vs SAMSUNG OLED S95F (QD-OLED)

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

The new generation of QD-OLED matrices in the Samsung S95F shows its full potential, with brightness results that are truly stunning. In test film scenes like "Life of Pi" or "Sicario 2," where smaller light elements appear – stars, the moon, or headlights – the television managed to achieve over 2000 nits of brightness. This is a result that surpasses even most top-of-the-range Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED televisions, here we have millions of emitting pixels, allowing the television to fully showcase its power without technological compromises. Of course, as this is still an organic panel, in full-screen scenes flooded with white – like in the final sequence of the film The Meg – the brightness drops to around 1400 nits. Nevertheless, the result remains excellent and clearly exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The colour reproduction is also particularly noteworthy. Thanks to QD-OLED technology, the television achieves nearly 100% coverage of the DCI-P3 colour space and about 80% in BT.2020. These values make HDR images not only dazzling in brightness but also captivating in the richness of colours.

On the Samsung S95D, the mode that best reproduces colours is the Filmmaker mode. We conduct all our tests in this mode. Although initially, the picture in this mode may appear slightly warmer to the viewer, it provides significantly more detail compared to the standard or dynamic mode, which is always oversaturated and artificial. The Filmmaker mode is therefore 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 errors that affect the overall quality of the displayed scenes. An example is drops in red colour in the white balance, both in HD and HDR content. Colour Checker tests showed that the hues lean towards cooler tones. The image is dominated by blue hues, and the entire colour spectrum is distorted. As can be seen in the picture below, the little boy from the film appears in cooler tones, making him look less natural. When it comes to the brightness characteristics for HD content, it is quite accurate, although there are minor errors. The biggest problem arises when displaying 4K HDR content. The EOTF curve, which seems appropriate at first glance in test patterns, shows that the television sometimes "messes" with the image in real film scenes. This causes the picture to be slightly brightened in some scenes and darkened in others.

Samsung S95D offers quite good factory colour reproduction, but 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 best picture mode straight out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years, designed to faithfully convey the creators' intent. In SDR content, its implementation is not bad, although some imperfections can be observed. The image is slightly dimmed, and the screen has a subtle pinkish tint due to the dominance of red and blue in the white balance. Colour errors were maintained at a level of 3–4 ΔE units – and for those who are not familiar: a value above 3 is the threshold at which the average human eye starts to notice differences.

However, much greater problems arise in HDR content. Here, the white balance was not such a significant issue – a slight excess of blue did not significantly hinder the viewing experience. The problem became managing brightness. In practice, the television "blasted" the image too much, causing details in the blacks to completely disappear. The final effect was far from expected, and colour errors in this mode became quite pronounced. It's hard to say why such a design decision was made, but it was evident that the factory HDR settings did not allow this television to showcase its full capabilities.

How much can the picture quality of a television change after calibration? After performing calibration on the Samsung S95D, the white balance was significantly improved, eliminating any major errors, which allowed for a more natural and harmonious colour reproduction. In the case of 4K content, there are only minor imperfections, which do not affect the overall picture quality. Thanks to calibration, viewers can now enjoy more balanced tones, allowing for a better representation of the filmmakers' intentions. The contrast has also improved, and the gamma shows even better results. This means that the differences between the light and dark areas of the image have become more pronounced, translating into better depth and detail in scenes. As a result, shadows gained more detail, and bright areas are no longer 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 television handles dynamic scenes. Nonetheless, after calibration, the overall picture quality has significantly improved, and viewers can now enjoy a visual experience that is more in line with the filmmakers' intentions. The television handles subtle tonal transitions and contrast better, making it more suitable for watching films and high-definition programmes. Ultimately, the picture after calibration is closely aligned with reference quality, making the visual experience even more satisfying.

After calibration, it was possible to make subtle adjustments to the white balance and significantly improve the image characteristics. In SDR content, the quality has become practically reference-level – most colour errors have fallen below a ΔE value of 1, which is the level at which the human eye can no longer discern differences. This is a result that places the S95F among the very best televisions available on the market.

In HDR materials, the calibration also brought about a significant improvement. The television's tendency to blow out highlights has been brought under control, as confirmed by the analysis of the EOTF curve. A slight tendency to brighten the entire scene or occasional loss of detail in blacks can still be observed, but this does not significantly affect the overall perception. After calibration, the S95F reveals its full potential and can be described as one of the best televisions on the market!

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.

Regarding digital processing, the entire image — from branches to model figures — has been well rendered, without any jagged edges or heavily visible contours. However, we must draw attention to one issue: the image is slightly cropped. Nevertheless, the television performs excellently, and details in lower-quality materials are still noticeable and well-defined.

The Samsung S95F offers a noise reduction feature that is responsible for smoothing tonal transitions. It works very effectively, but in practice, it can be overly aggressive. Materials of lower quality – e.g., older recordings or videos from YouTube – become soft and plastic when this feature is activated, resembling an image digitally smoothed in a graphic program. Unfortunately, the natural film grain, which often adds authenticity to the image, disappears in the process. Fortunately, the television does not lose too many fine details, such as in skin textures or elements of the surroundings. Therefore, this feature is best used with discretion – depending on preferences, one can achieve a smooth image that is less natural, or one that is truer to the original. In our opinion, the most universal choice is the “Standard” setting.

The image scaling performs significantly better. The television handles materials of lower resolution well – even content at 576p looks quite decent, although a slight blockiness can be noticed. Overall, the effect is very good, although it somewhat falls short of what Sony Bravia 8 (II) or LG G5 can achieve. It is also worth mentioning a minor imperfection of the S95F – in older materials, overscan may occur, causing a slight trimming of the left edge of the image.

The Samsung S95D television, equipped with a refresh rate of 120 Hz (and even 144 Hz in the appropriate PC configuration), offers excellent motion smoothness. Samsung provides a variety of image sharpness settings on a ten-point scale, allowing users to adjust the display according to their preferences - whether the image should be more cinematic/frame-like or more theatrical/smooth. In UFO tests, the OLED matrix shows its advantages, eliminating any blurring. The lightning-fast pixel response means that dynamic movements are reproduced with unparalleled precision.

The Samsung S95F shows phenomenal performance in terms of motion fluidity. The panel operates at a native resolution of 4K with a refresh rate of up to 165 Hz, and combined with QD-OLED organic technology, it delivers incredible results. Sports and games look stunning – the image is fast, dynamic, and very natural. Additionally, the built-in motion smoother and motion blur reduction system allow you to tailor the character of the picture to your own preferences. You can opt for a more "frame-like" effect with visible film structure or a smooth, theatrical spectacle. Every viewer will find a setting that suits them.

The Samsung S95D TV is perfectly suited to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). The HDMI 2.1 ports do not provide full bandwidth of 48Gb, but they are still sufficient for achieving appropriate resolution and smoothness. Thanks to these technologies, gamers can enjoy smoother and more responsive gameplay, which significantly impacts comfort and performance during intense gaming sessions. One of the biggest advantages is the Xbox app, which allows for cloud gaming without the need for a console. Through it, gamers can access a wide range of titles directly on the TV, enjoying high image quality and smooth gameplay. Additionally, the S95D offers a Game Bar feature that enables easy management of game settings, including quick adjustments of parameters such as changing the aspect ratio, which can be extremely useful in various games and gaming modes. It is also worth mentioning the support for G-Sync and FreeSync, which is a huge plus for users of Nvidia and AMD graphics cards. Despite the lack of support for Dolby Vision, the TV still offers excellent features that make it an ideal choice for console gaming enthusiasts. Overall, the S95D combines modern technologies with outstanding picture quality, creating a complete package for any gamer.

The advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F has been designed with gamers in mind. The manufacturer has equipped it with four HDMI 2.1 ports – although limited to a bandwidth of 40 Gb/s, in practice this has no impact on compatibility with consoles or PCs. We get a full suite of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, which ensures that HDR titles look exactly as their creators intended. Completing the package is the Game Bar – a clear settings hub where we can preview and change all key image parameters with one motion. The proprietary motion smoother, Game Motion Plus, also deserves commendation, as it can smooth out animations, which is particularly useful in productions running at 60 frames, where stability is not always exemplary. While support for Dolby Vision in games is lacking, it’s hard to view this as a serious drawback – Samsung compensates with other solutions. This is one of the best, if not the best, gaming televisions available on the market today.
