Philips PUS8079 vs LG OLED G6 (G64LW, G66LS)

The Philips PUS8079 has a maximum brightness of just 202 nits in content with a wide tonal range, which is very low and makes it unsuitable for streaming movies and series in the highest quality. Additionally, using HDR with dynamic metadata doesn’t improve the situation, as the only HDR format available on this model is HDR10+, which is rare and has limited content support. The TV also uses WLED backlighting, which is not optimal and results in only 80% coverage of the DCI-P3 wide colour gamut. This limits the intensity of colours in 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 best factory mode for colour reproduction and fidelity to the director's vision on the Philips PUS8079 was the "Film" mode. However, this setting displayed significant discrepancies between the filmmaker's intent and the actual output. In both SDR and HDR materials (with HDR being less affected), the white balance was off, showing a blue tint similar to store displays, rather than pure whites. When it came to SDR materials, gamma was notably lowered, cutting into the already limited contrast and brightening the overall image. The EOTF curve in HDR content also showed a significant drop below the reference line, making HDR materials appear even darker. The colour accuracy in both SDR and HDR modes was poor, with high deltaE values indicating that the colours were far from their intended representation.

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.

Fortunately, Philips incorporates advanced image correction tools across its televisions. SDR content benefited the most from these adjustments, with significant improvements in deltaE errors, white balance, and gamma. While the image still isn’t perfect, it is much more watchable, making it easier on the eyes during movie or series viewing. HDR content, however, was more challenging due to the television’s low luminance. While the EOTF curve and white balance improved, the corrections weren’t as effective as with SDR materials. It’s important to note that each unit may have different errors, some larger and some smaller, but the adjustments made were a step in the right direction.

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.

Let us revisit the topic of tonal transitions, this time in the context of overall image quality enhancement. As shown in the photo on the left, the gradation improvement feature delivers excellent results. It provides multiple settings, each offering noticeable benefits without softening the film grain effect. Once again, it must be emphasised that this feature is the standout advantage of the tested television.

On the other hand, the television’s performance in image scaling leaves much to be desired. Fine details often appear heavily jagged, with a noticeable white halo around figures. Additionally, the significant artificial sharpening detracts from the overall image quality.

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.

This paragraph will be notably brief due to the absence of even basic motion-smoothing functionality, which is unsurprising given the device's budget-oriented nature. The VA panel used here is not known for exceptional sharpness and is instead associated with high contrast and slower response times, as confirmed by the matrix analysis results. Photos captured during fast motion reveal typical motion blur for this type of panel. While not ideal, the television could be conditionally suitable for watching sports, though viewers should expect less-than-optimal motion clarity. Additionally, films may exhibit noticeable stuttering due to the lack of any motion-smoothing features, even basic ones.

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 Philips PUS8079 provides only basic gaming features, including ALLM, VRR, and a Game Bar. The key highlight is the inclusion of dynamic frequency adjustment, which ensures a smooth image with minimal screen tearing—an impressive offering for this price range.

A notable benefit for gamers is the presence of the Game Bar, allowing adjustments to be made "on the fly" without needing to exit the game. Importantly, this feature retains options found in higher-end models, such as shadow enhancement for improved visibility in darker areas and a colour filter designed to assist gamers with visual impairments.

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.
