Samsung OLED S95D vs Samsung S85F (WOLED)

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%.

For most of the time, let's say in 90% of film scenes, viewers won't see practically any difference between the S85F versions. When small but very strong light points appear on the screen – a lantern in a dark alley, a gunshot, the sun breaking through the clouds – this WOLED panel (like the smaller S85F) performs wonderfully. Our measurements showed peak brightness at around 750 nits. We can confidently state: this is an excellent result that guarantees fantastic HDR effects. The problem arises in a very specific, uncomfortable situation for any OLED. We're talking about the moment when the entire screen has to shine at full power brightly. Examples include a slide with a white background, a ski jump scene, or our test sequences (5) from the movie The Meg. And here, unfortunately, the results diverge quite significantly to the detriment of the WOLED panel variant. Our measurement equipment was able to measure a maximum of about 250 to 300 nits of brightness in such conditions. Just to be clear: the same model on a QD-OLED panel in the same test is almost twice as bright. The second issue: colors. And here we also have to be honest – QD-OLED has a design advantage. Why? It’s simple. QD-OLED creates colors from three components (red, green, and blue) and does not need an additional white subpixel. The WOLED panel we are testing uses this white subpixel mainly to boost overall brightness. The effect is that QD-OLED is able to show a slightly wider color palette, and the colors are a bit "cleaner." But let’s be clear: it’s not that the colors on this WOLED panel are bad! On the contrary, they are actually very good. Coverage of the DCI-P3 film palette at 97% and 71% for the wider BT.2020 palette is still a high standard. We just have to honestly admit that this few percent advantage in color coverage is on the side of QD-OLED technology and may be noticeable in very specific moments.

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.

When it comes to factory color reproduction, our test sample in SDR mode suffered from a slight deficiency in red and yellow color. This resulted in a subtle yellowish tint visible in the shades of white. However, this is not the biggest problem with the S85F. Similar to the QD-OLED panel variant, the biggest issue with this model is the way it presents HDR content. When we look at the EOTF curve graph, it is easy to see that the television has quite significant problems with overly brightening the image. This causes the final picture in many scenes to become very unnatural.

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 in Filmmaker mode, we managed to eliminate most of the unwanted effects. In SDR content, the television performs exemplary, and its color reproduction errors do not exceed a value of 2, which is an excellent result. A bit worse, although still very good, are the HDR quality contents. While we were able to eliminate a significant unnaturalness in the image caused by too high a positioning of the EOTF curve, the most discerning observers may notice that it is not perfectly aligned. It runs slightly below the reference curve, which would suggest that the S85F has slight issues showing all the details in the image. We must point out right away that it is highly unlikely that an average viewer would notice any shortcomings in the image. The final effect after calibration is rated as exemplary.

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 processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterization (the "stepping" effect of colors), even with heavily compressed materials, such as from streaming services. However, using this feature requires making a certain compromise. We noticed that the noise reduction algorithm is quite aggressive – even at the lowest setting, it can eliminate natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be the golden mean, not causing visible loss of important details, so we can recommend it. However, we advise against using the "High" level, which removes not only noise but also desired details, such as texture or structure of objects on the screen.

The scaling (upscaling) process of lower resolution content works very well in the S85F. The image is sharp and clear. The only minor imperfection we observed is occasional, slight aliasing on the edges. The television also still exhibits characteristics typical of this manufacturer, such as active "overscan" (slight magnification of the image). This should be kept in mind, especially when watching older materials, as it may result in a minimal cropping of the original frame.

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 S85F is a model with impressive speed. The use of a 120 Hz OLED panel ensures that dynamic scenes, both in games and during sports broadcasts, meet expectations: smoothly, sharply, and without loss of clarity. A key role here is played by the instantaneous pixel response time, which is a natural advantage of OLED technology. Transitions between frames are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, like a ball on the field or a car in a chase scene, are clear and devoid of the characteristic motion blur typical of LCD panels (the so-called "tail").

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.

85F has practically everything on board to become the ultimate screen for gaming. It features four full HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode). Additionally, it includes a super-detailed Game Bar that clearly displays all key parameters. However, the true gem is the Game Motion Plus feature. This motion smoother dedicated to games makes animations more pleasant to the eyes while only slightly increasing input lag. This is a rare and well-functioning combination, deserving of high praise for Samsung.

And now comes the moment when we have to complain a bit. The absence of Dolby Vision in Samsung TVs has become standard, so there's no use hoping (unless something changes in the future). Unfortunately, it's much harder to explain the disappearance of support for HGiG after one of the software updates. HGiG (HDR Gaming Interest Group) is a crucial mode that allows for precise brightness representation in HDR games, according to the developers' intent. Without it, HDR calibration on the console becomes less precise, which can result in images that are too dark in the shadows or overly bright in the highlights. Perhaps Samsung will fix this in the next update – we have high hopes for that. Because if HGiG returns, S85F will become an almost perfect gaming TV.
