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

Samsung S95D offers excellent HDR performance, providing uniform effects across all scenes exceeding 1500 nits, except for the fifth scene, where brightness drops to 800 nits. Despite this, the television maintains a high level of image quality. A significant advantage of QD-OLED technology is its ability to retain high brightness even in the smallest elements on a black background, which is uncommon in LCD and mini LED televisions. This ensures that every scene captivates with strong light effects, regardless of the size of the illuminated surface. Only in the brightest scenes with large light areas does brightness slightly decrease, which is typical even for standard LG-produced OLEDs. Additionally, the quantum dot coating has allowed for unprecedented high coverage of the BT.2020 colour gamut at 88%.

The new generation of QD-OLED panels in the Samsung S95F shows its full potential, and the brightness results are absolutely stunning. In test film scenes, such as "Life of Pi" or "Sicario 2," where smaller light elements appear – stars, the moon, or headlights – the TV was able to achieve over 2000 nits of brightness. This is a result that surpasses even most top Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED TVs, we have millions of glowing pixels here, allowing the TV to fully showcase its power without technological compromises. Of course, since it 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 definitely exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The color reproduction also deserves special attention. Thanks to QD-OLED technology, the TV achieves almost 100% coverage of the DCI-P3 color palette and about 80% in BT.2020. These values make the HDR image not only dazzling with brightness but also captivating with a richness of colors.

The Samsung S95D’s Filmmaker mode excels in colour accuracy, making it ideal for true-to-life viewing and closely reflecting the intent of content creators. We rely on this mode for all testing, as it presents significantly more detail than the often oversaturated standard or dynamic modes. Initially, viewers may find the image slightly warmer in Filmmaker mode, but it brings out a more authentic, balanced display. Despite being in the premium segment, the factory settings aren’t perfect. For example, there is a dip in red tones in the white balance for both HD and HDR content, with Colour Checker tests showing a cooler colour bias that shifts the image towards blue, impacting the natural appearance of scenes. In the sample photo, the boy appears in cooler tones, which diminishes realism.

Brightness performance for HD content is generally on point, though minor inconsistencies appear. However, the more noticeable issue arises with 4K HDR content. While the EOTF curve seems accurate in test patterns, real scenes sometimes reveal fluctuations, where some areas are overly brightened or darkened. Although the S95D offers reasonably good out-of-the-box colour reproduction, calibration is recommended to achieve a more precise, natural, and immersive picture, maximising the television’s potential.

The best picture mode right out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years, designed to faithfully represent the creators' intentions. In SDR content, its implementation is not bad, although some imperfections can be noticed. The picture is slightly dimmed, and the screen has a slight pinkish tint resulting from the predominance of red and blue in the white balance. Color errors remained at a level of 3–4 ΔE units – and for the uninitiated: a value above 3 is the threshold where the average human eye begins to notice differences.

However, much larger problems arise in HDR content. Here, the white balance was not such a significant issue – a slight excess of blue did not cause major problems. The issue became managing brightness. In practice, the TV "overexposed" the image too much, causing details in the blacks to completely disappear. The final effect was far from what was expected, and the color errors in this mode became really large. It's hard to say why such a design decision was made, but it was clear that the factory HDR settings did not allow this TV to showcase its full potential.

Calibration can significantly elevate a television's image quality, enhancing both accuracy and overall viewing experience. For the Samsung S95D, calibration has notably refined the white balance, removing major colour inaccuracies to produce more natural and balanced tones, which allows for a closer representation of the filmmakers’ vision. The adjustments bring subtle improvements to contrast and gamma, with more pronounced distinctions between light and dark areas, adding depth and revealing finer details in both shadows and highlights. This creates a richer, more lifelike image with enhanced detail, particularly in darker scenes where shadows now hold greater clarity, while bright areas appear well-balanced rather than overly intense.

Despite these improvements, the EOTF curve remains slightly below ideal, which might influence the handling of dynamic scenes. However, the enhanced tonal transitions and boosted contrast post-calibration make the S95D an excellent choice for film and high-definition content, bringing it closer to reference-level quality. This calibration enables the television to deliver a more immersive, accurate visual experience in line with industry standards, ultimately offering a more rewarding viewing experience.

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

In HDR materials, calibration also brought significant improvement. The tendency of the television to overexpose the image was successfully controlled, as confirmed by the analysis of the EOTF curve. A slight tendency to brighten the entire scene or occasional loss of details in the blacks can still be observed; however, it does not significantly impact the overall perception. After calibration, the S95F showcases its full potential and can be described as one of the best televisions on the market!

The Samsung S95D handles tonal transitions in lower-quality materials exceptionally well. In tests featuring a screen with a light bulb, there are virtually unnoticeable transitions between shades of grey, positioning it among the best televisions we have evaluated in this aspect.

Regarding digital processing, the S95D excels in rendering the entire image—whether it's branches or figures—without any jagged edges or overly pronounced contours. However, one point to note is that the image appears slightly trimmed. Despite this minor issue, the television still performs admirably, ensuring that details in lower-quality materials remain noticeable and well-defined. This ability to maintain clarity and depth in various content types further solidifies the S95D's reputation for delivering a high-quality viewing experience.

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

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

The Samsung S95D TV, featuring a refresh rate of 120 Hz (and even 144 Hz when configured correctly for PC use), guarantees exceptional motion smoothness. Samsung provides a range of image sharpness settings on a ten-point scale, enabling users to customise the display according to their preferences— favouring a more cinematic look or a smoother, theatrical feel.

In UFO tests, the OLED panel demonstrates its strengths by effectively eliminating any blurring. The rapid pixel response ensures that dynamic movements are replicated with remarkable precision, resulting in a fluid viewing experience that enhances fast-paced content, such as action films or competitive gaming. This combination of high refresh rates and superior pixel response makes the S95D an outstanding choice for those seeking crisp, clear motion in their visual media.

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

The Samsung S95D TV is expertly designed to meet the needs of gamers, featuring four HDMI 2.1 ports that support essential functionalities like Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). While the HDMI 2.1 ports do not offer the full 48Gb bandwidth, they are still adequate for achieving the desired resolution and smooth performance.

These technologies enable players to experience smoother and more responsive gameplay, significantly enhancing comfort and performance during intense gaming sessions. A standout feature is the Xbox app, which facilitates cloud gaming without requiring a console. This allows gamers to access an extensive range of titles directly on the TV, enjoying high image quality and fluid gameplay.

Additionally, the S95D includes a Game Bar feature, making it easy to manage game settings with quick adjustments, such as changing the screen ratio—an extremely useful function for various games and gameplay modes. The support for G-Sync and FreeSync is another advantage, particularly for Nvidia and AMD graphics card users.

Although the S95D lacks support for Dolby Vision, it still provides an impressive array of features, making it an ideal choice for console gaming enthusiasts. Overall, the S95D combines cutting-edge technology with exceptional picture quality, creating a comprehensive package for any gamer seeking an immersive experience.

The same advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F was 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 complete set of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, which allows HDR titles to appear as their creators intended. The whole thing is complemented by the Game Bar – a clear settings hub where we can preview and change all key picture parameters with one movement. The proprietary motion smoother Game Motion Plus also deserves praise, as it can smooth out animation, which is particularly useful in productions running at 60 frames, where stability is not always exemplary. Although support for Dolby Vision in games is lacking, it is hard to consider this a serious drawback – Samsung compensates for it with other solutions. This is one of the best, if not the best, gaming TVs available today on the market.
