SAMSUNG OLED S95F (QD-OLED) vs TCL C6KS / C69KS / Q6CS

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.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

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.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

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!

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

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 C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

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.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

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.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
