Samsung Neo QLED QN95D vs LG OLED G6 (G64LW, G66LS)

The Samsung QN95D excels in HDR performance, achieving an impressive peak brightness of approximately 2000 nits. In tested movie scenes with fully lit screens, the television delivers an intense and realistic representation of HDR content, significantly enhancing the viewing experience. However, as with its handling of contrast, the dimming algorithm occasionally reveals limitations.

Despite the large number of Mini LED zones, the television doesn’t consistently provide extraordinary brightness. For instance, in scenes from "Life of Pi," featuring a bright moon against a dark background, and excerpts from "Sicario 2," showcasing intense light effects on dark backdrops, the QN95D underperforms. In such instances, the television mitigates halo effects by dimming the image to a level closer to SDR quality. While this ensures deep and uniform blacks, it comes at the cost of losing some detail in bright areas. This compromise is intended to preserve black quality but can detract from the image’s dynamism.

Despite these occasional shortcomings in the local dimming algorithm, the QN95D deserves commendation for its wide coverage of the DCI-P3 colour gamut. Thanks to the quantum dot coating, also known as QLED technology, the television produces vibrant and richly saturated colours, adding to its appeal for HDR content.

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 Samsung QN95D was evaluated for factory colour reproduction in Filmmaker mode, which provides the manufacturer’s optimised settings. While this mode delivers good performance, it is not without shortcomings. For HD content, notable colour deviations were observed, particularly in white balance, where a red tint dominated the chart. Improvements were noted with 4K HDR content; however, significant deficiencies in blue colour reproduction persist. This is evident in scenes such as those from Star Wars, where the main character appears in tones that are warmer than intended.

Regarding contrast, the gamma chart reveals an initial steep rise, demonstrating the television’s capability to emphasise brighter image areas effectively. However, the chart also shows a clear dip at the lower end, suggesting a potential loss of detail in darker tones. This gamma curve shape could impact the clarity of dark scenes, where details may appear overly blurred or obscured. Additionally, the brightness curve (EOTF) was mostly accurate, aside from an initial drop.

Despite these minor issues, the QN95D boasts impressive features and cutting-edge technology that solidify its position as one of the top televisions on the market. However, refinements in colour accuracy and contrast are needed to maximise its potential fully.

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 calibration, the Samsung QN95D delivers truly impressive results. The white balance is perfectly aligned, with error readings rarely exceeding 2, indicating faithful colour reproduction. Most samples from the Colour Checker test fall well within an acceptable error range, confirming the television's excellent performance in accurately displaying colours. Contrast has also improved significantly, and the gamma curve has become more stable, ensuring better visibility of details in both dark and bright scenes.

However, the EOTF (Electro-Optical Transfer Function) curve still shows a slight divergence in film tests. While the television performs well in most scenarios, some details in black may still be lost in extreme cases due to the aggressive dimming algorithm.

Despite these minor imperfections, the overall image quality remains outstanding. After calibration, the Samsung QN95D impresses with its visual performance, offering an exceptional experience that will satisfy anyone seeking a top-tier television.

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 QN95D television handles tonal transitions even in lower-quality materials, thanks to the noise reduction feature that works like a gentle gradation. This function is extremely effective, smoothing out the image and eliminating unwanted noise, thus significantly improving the quality of the displayed material. However, as is often the case, overly good effectiveness can lead to unintended side effects. In the case of some materials, this feature may also blur elements that should remain clear, such as film grain.

Despite this, the television performs well in terms of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not overly artificially sharpened, which allows for a natural look, and the model does not have an artificial outline. Overall, even in more challenging conditions, the footage is presented satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (such as regular terrestrial television) is the fact that the image is slightly cropped - this is caused by the so-called overscan, which cannot be turned off.

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 QN95D panel excels in motion blur and fluidity, offering a 120 Hz refresh rate along with features designed to reduce blur and judder. This allows users to adjust the picture settings to their liking, whether for movie watching or dynamic sports broadcasts. The television provides a 10-point scale for adjusting image smoothness, ranging from a frame-like appearance reminiscent of traditional film to a smoother, more cinematic effect, which is especially beneficial for sports broadcasts. This level of customization enhances the viewing experience across various types of content.

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 Samsung QN95D offers several features that gamers will appreciate. First, the TV supports a variable refresh rate (VRR), which eliminates screen tearing and provides smoother gameplay, especially in dynamic scenes. It also includes an automatic game mode (ALLM) that switches the TV to low latency mode when a connected console or computer is detected, resulting in more responsive controls.

Additionally, the QN95D has a game mode that reduces input lag to an impressively low level, which is vital for games where quick reflexes matter. With a high refresh rate of 120 Hz, the image remains exceptionally smooth, enhancing the experience of fast-paced action games and sports. The TV also supports G-Sync and FreeSync technologies, further improving gameplay and user comfort. An interesting addition is the 'Game Bar' – a special menu that provides easy access to all gaming-related settings, allowing users to quickly adjust the image and other parameters without interrupting gameplay.

While the Samsung QN95D does not support Dolby Vision, which is typical for Samsung models, it does feature HGiG functionality, ensuring that HDR games are displayed with the appropriate image quality in line with the creators' intentions.

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.
