SAMSUNG OLED S95F (QD-OLED) vs LG OLED G6 (G64LW, G66LS)

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 LG G6 is currently one of the brightest OLEDs on the market. Its peak brightness reaches nearly 2500 nits, and best of all – this has a direct impact on real film scenes. The television flawlessly pulls out details in the bright parts of the image. And this is regardless of whether we are talking about very small points like stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 decreases due to the panel's protection system (ABL). However, in real, varied film shots, this value still hovers around 2000 nits, which can be considered an outstanding result. The coverage of the color palette also deserves praise. The new 2nd generation Tandem OLED panel brought only a cosmetic change, but still an improvement. The DCI-P3 color gamut coverage reaches nearly 99.5%, while the ultra-wide BT.2020 is around 84%. These are very good results, although one must remember one thing: at extremely high brightness levels, the volume of colors will be lower than in QD-OLED panels from Samsung Display due to the use of a white sub-pixel (WOLED). However, in everyday content and most films, detecting this difference will be very difficult.

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.

We tested the LG G6 in the best factory mode for color fidelity, which is FILMMAKER MODE. For our test unit, this mode was fairly well-tuned right out of the box. In SDR content, the only thing we could nitpick was the white balance, which leaned towards warmer tones. As a result, the image could sometimes appear slightly yellowed; however, overall, it wasn't a bothersome issue. The G6 performed a bit worse with HDR content. There, we noticed too much blue component in the white balance. This caused the image to take on cooler shades, resulting in quite noticeable errors. As can be seen in our ColorChecker chart, colors were indeed shifting towards these cooler registers. Nevertheless, for factory settings, the television displayed a completely decent level. However, we know that OLED screens – especially those from LG – respond wonderfully to professional calibration, which is why we immediately proceeded with it.

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!

After conducting a professional calibration, we gained complete control over the panel, and we were able to adjust all parameters to nearly zero. We managed to perfectly tune the white balance, which made the factory-cool and warm tints disappear from the screen. The effects are clearly evident in the ColorChecker test – the average color reproduction errors dropped below the critical value of 1-2. And what does that mean? PERFECT colors, with no distortion whatsoever! However, from a reviewer's obligation, we must comment on how the LG G6 autonomously manipulates brightness, for which the EOTF curve is responsible. When we look at the standard synthetic graph, it may seem that the line is quite straight. The situation changes, however, when we turn on the measurement filter, which shows how the television interprets brightness in real, moving film scenes (EOTF in MOVIES). At that point, it becomes clear that some of the smallest fragments on the screen are slightly over-brightened by the algorithm. Of course, for the average viewer, such a deviation will be practically unnoticeable, but in the test of such an expensive screen, it is worth noting – especially since we are talking about a model that has huge aspirations to be the best television of the year.

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.

No matter what one may say about the G6's problems with near-black signal, it must be fairly acknowledged that it handles highly compressed material and lower resolution content brilliantly. All unwanted, ugly tonal transitions are effectively reduced here by the “Smooth Gradation” feature. On the “Low” setting, the algorithm operates flawlessly – effectively masking the artifacts resulting from strong compression, without destroying the sharpness and details in the frame. Higher levels of this feature indeed smooth the image even more, but they start to blur the real texture elements of objects, which is why we recommend keeping this slider at a low level. As for the upscaling to 4K, the processor does an excellent job – edge sharpness and detail reconstruction are at the highest level, and in this respect, the G6 does not lag behind the world's best.

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 LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest ratings. The television supports a very high refresh rate of up to 165 Hz in 4K resolution, but most importantly – you will not see any signs of blurring on the screen. The response time of the panel is incredibly fast, ensuring that dynamic images remain perfectly sharp.

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.

LG G6 is a true monster for gamers and one of the best-equipped TVs in this regard on the market. The manufacturer did not seek compromises and equipped this model with as many as four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This means that no matter which port you plug your PlayStation 5, Xbox Series X, or powerful PC into, you will extract the absolute maximum from them.

The TV supports a full suite of gaming technologies: from VRR (Variable Refresh Rate), through AMD FreeSync Premium Pro, to Nvidia G-Sync Compatible. Let's add to this the remarkably low, almost imperceptible input lag and a brilliantly functioning gamer panel (Game Optimizer), which allows you to continuously monitor the signal parameters. Gaming on this screen, with the perfect black of OLED and powerful refresh rates, is pure pleasure.
