SAMSUNG S90F (WOLED) vs SAMSUNG OLED S95F (QD-OLED)

Does the S90F handle not only blacks but also bright parts of the image? Definitely. The stories about OLEDs as "dark screens" can slowly be regarded as myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value more than enough to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test card from the movie The Meg (photo 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be said that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

The new generation of QD-OLED panels in Samsung's S95F showcases its full potential, and the brightness results are simply astounding. In test film scenes, such as “Life of Pi” or “Sicario 2”, where smaller light elements appear – stars, the moon, or spotlights – the television managed 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 televisions, here we have millions of glowing pixels, allowing the television to fully demonstrate its power without technological compromises. Of course, since it is still an organic panel, in scenes that are full-screen and flooded with white – like in the final sequence from The Meg – 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 colour reproduction is also particularly noteworthy. Thanks to QD-OLED technology, the television achieves almost 100% coverage of the DCI-P3 colour space and around 80% in BT.2020. These values make HDR images not only dazzling in brightness but also stunning in their range of colours.

Samsung S90F, like most modern televisions, offers many picture modes, but – following our testing tradition – we checked it out in the best one, which is the Filmmaker mode. Thanks to this, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially dimmed – simply closer to what one should see. Of course, “more accurate” doesn’t mean “perfect”. Unfortunately, our S90F had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more “filmic” – because it’s warmer – but let’s not kid ourselves, George Lucas didn’t film Star Wars in sepia 😉 (you’ll find a comparison with the scene below as always).

Additionally, in HDR materials, there was an issue with brightness management. The EOTF curve showed a clear “spike” in brightness – the television brightened the image more than it should have, causing some effects to look too intense and deviating from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you’ll read about its effects later in the review.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years and which is intended to faithfully convey the creators' vision. In SDR content, its implementation is not bad, although some imperfections can be noticed. The image is slightly dimmed, and the screen has a subtle pinkish hue resulting from an excess of red and blue in the white balance. Colour 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 starts to notice differences.

Much bigger problems arise in HDR content, however. Here, the white balance was not as much of an issue – a slight excess of blue did not significantly hinder things. The problem became brightness management. In practice, the TV "blows out" the image too much, causing details in the blacks to completely disappear. The final effect was far from what was expected, and the colour errors in this mode became quite significant. It’s hard to say why such a design decision was made, but it was clear that the factory HDR settings do not allow this TV to showcase its full potential.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older movies in SDR quality finally look like they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is back in place (no thanks needed, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Admittedly, the most demanding users may detect minimal deviations in brightness, but honestly – most viewers won't even notice that. And it's no surprise because the vast majority of errors fall below the ΔE 3 value, which is below the threshold of visibility. After calibration, the S90F (WOLED) becomes a truly excellent display – one on which you can enjoy nearly perfect image quality.

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 dropped below a ΔE value of 1, which is the level at which the human eye can no longer perceive differences. This is a result that places the S95F among the absolute top TV models available on the market.

In HDR material, calibration also brought a significant improvement. The tendency of the TV to blow out the image was managed, as confirmed by the analysis of the EOTF curve. There is still a slight tendency to brighten the entire scene or occasional loss of detail in the blacks, but this does not significantly affect the overall perception. After calibration, the S95F shows its full potential and can be regarded as one of the best TVs on the market!

Digital Image Processing in S90F:

Fortunately, Samsung, like in most of its models, manages to effectively tackle the unwanted posterisation effect in the S90F. The function responsible for this element is noise reduction, which does a pretty good job of smoothing tonal transitions and eliminating unnatural colour blending – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with trade-offs. In addition to improving gradation, it can also remove film grain or slightly soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you care about preserving the original texture of the material.

Image Scaling in S90F:

In this year's model, Samsung has implemented its proprietary AI processor – NQ4 Gen3, which really handles upscaling quite well. In our test scenes, the TV effectively "pulled up" lower quality towards artificial 4K – the image was more enjoyable to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing façade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival material – e.g. a VHS tape of your parents' wedding – you have to reckon with the fact that the lower part of the image may get cut off. The function to adapt the image to resolution simply does not work as it should here.

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 – e.g. older recordings or videos from YouTube – become soft and plastic when it is enabled, resembling an image digitally smoothed in graphic software. Unfortunately, the natural film grain, which often adds authenticity to the image, disappears in the process. Fortunately, the television does not lose too much fine detail, e.g. in skin textures or environmental elements. Therefore, this feature is best used judiciously – depending on preferences, one can achieve a smooth but less natural image or one that is truer to the original. In our opinion, the most universal choice is the “Standard” setting.

Image scaling performs significantly better. The television handles lower resolution materials well – even 576p content looks quite decent, though slight blockiness can be observed. Overall, the effect is very good, although it slightly trails behind 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 trimming of the left edge of the image.

S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is smooth, clear, and there’s no room for ghosting or blurring, which can sometimes plague cheaper LCDs.

The TV also comes equipped with motion smoothness settings that allow you to customise everything to your liking. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to the point of looking a bit soap opera-like), or more cinematic, with the classic “jumpiness” of 24 frames. The choice is yours, Samsung imposes nothing.

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

When it comes to gaming features – the S90F has absolutely nothing to complain about. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus deserves special mention – Samsung's proprietary motion smoother that actually works sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It's also worth mentioning the HGiG feature, which – and this may be a slight surprise – works correctly. We bring this up because Samsung clearly messed something up in one of the recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes almost impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for new software versions and information from the manufacturer.

The same 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 – though limited to a bandwidth of 40 Gb/s, in practice, this has no impact on compatibility with consoles or PCs. We get a full package of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, ensuring that HDR titles look as the creators intended. This is complemented by Game Bar – a clear settings hub, where with one motion, we can preview and change all key image parameters. The proprietary motion smoother Game Motion Plus also deserves praise, as it can smooth out animation, which is especially useful in productions running at 60 frames, where stability is not always exemplary. While there is no support for Dolby Vision in games, it’s hard to consider this a serious drawback – Samsung compensates with other solutions. This is one of the best, if not the best, gaming TVs available on the market today.
