Philips PUS8359 (VA) vs LG OLED B6

Philips PUS8359 did not impress us with its results in HDR materials. This model is capable of generating a maximum brightness of 320 nits, and often even less. Such results, combined with a lack of support for HDR Dolby Vision, mean that the image will be significantly darker compared to the source material. Therefore, playing SDR materials will be more beneficial for this television. This is also suggested by the rather low coverage of the DCI-P3 colour gamut at 83%, which results in significant colour deficiencies. The fact remains that the television supports the HDR format based on dynamic metadata, although HDR10+ is such a niche format that it does not bring any significant advantages.

The LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year’s B5. That’s down to the new, budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR look fuller in many scenes than on last year’s lower‑end OLEDs. That does not mean the B6 has no limitations. In very bright shots, when a large part of the screen is strongly lit, brightness can fall below 400 nits. This behaviour is typical for OLED TVs, especially in this segment, and that’s where you see the biggest difference compared with more expensive models. Even so, we judge the B6’s results as genuinely solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that films truly feel like a step up from ordinary SDR. Colour gamut Using the OLED SE panel has had a slight impact on wide colour gamut coverage. Compared with last year’s model the results have fallen by a few percentage points. It covers roughly 96% of DCI‑P3 and about 71% of BT.2020. That doesn’t mean the colours on the LG B6 are weak. In most films and series they look lively, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD‑OLED panels. This stems from the WOLED panel structure. Besides red, green and blue subpixels it also uses a white subpixel, which helps to boost brightness. However, this comes at a price. At very high luminance some colour is effectively 'diluted' by the white light, so the saturation of certain colours can be slightly lower. In everyday use this isn’t a major issue, but in the most demanding scenes you can notice it.

The best factory mode in terms of fidelity to the source material was "Film". This was the mode we used during our tests. Just like each of the factory modes in televisions, it had its shortcomings. We will check what exactly was wrong in both SDR and HDR materials. In both cases, the white balance showed excessive dominance of the green and red colour combination. This created a yellow tint that spread across the entire image, causing issues such as yellowed whites and problems with skin tones. This situation was perfectly illustrated on the "ColourChecker" palette, where each of the tested samples was pushed into its warmer counterparts. The foundation of the image is primarily contrast and black. These are represented by gamma charts and the EOTF curve. Looking at the first one, we can see a true rollercoaster, as we can observe both an elevated and a lowered gamma. The heavily elevated gamma caused visibility issues in blacks, while the lowered gamma led to a dramatic drop in contrast. In this context, the EOTF curve performed significantly better, only slightly brightening the image.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes produce very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is, in any case, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. On SDR material the factory settings perform really well. Colour errors are small, the gamma response is correct, and the picture during normal viewing looks natural and does not feel overly "pumped up". It's a bit worse with HDR. When such content is played you quickly see that the white balance hasn't been set perfectly. Too much blue and red gives the image a slightly pink tint. This is also confirmed by colour gamut measurements and the ColorChecker, where samples clearly shift in that direction. It's not a flaw that completely spoils the picture, but it is noticeable with HDR films. Therefore anyone who wants the most faithful image should consider calibration, which we cover further on in the review.

Philips offers a wide range of image calibration tools in both its more expensive and cheaper models. We utilised these tools and got to work, which was not as easy as many of you might think. While we were able to model the white balance, significantly improve the gamma, and refine the EOTF curve in both cases, the deltaE errors remained extremely high. There are several reasons for this situation, which are directly related to the low coverage of the DCI-P3 palette and the maximum brightness of the unit in HDR materials.

During calibration, we concentrated mainly on HDR content, because that's where the factory settings needed the most correction. We did not, however, neglect SDR mode, which after adjustment was brought almost to perfection. Colours are very accurate, and brightness is controlled as it should be. The biggest improvement in HDR came from fixing the white balance. Removing the excess red and blue eliminated the pinkish tint, and the image became much more natural. Skin tones, whites and all colours that had previously shifted towards pink improved. After calibration most errors fell below a Delta E of 2–3, the threshold at which the average viewer stops noticing differences with the naked eye. So the LG B6 can deliver a very accurate picture, particularly for the manufacturer's entry-level OLED model.

In this paragraph, we will take a look at two functionalities. We will once again examine the feature responsible for tonal transitions, but we will also check how the television performs with image scaling. The option responsible for smooth gradation is called "Distortion Reduction". As we have established, it quite effectively smooths out the inconsistencies. However, we must point out two things: we cannot enable it for HDR materials and that it blurs details in films.

The tested television cannot boast of the best image scaling. There is a noticeable overall blurriness of the image, but worse still, it blurs details. This is particularly evident on the branches and the model's hair. A characteristic white halo around the character is also visible.

The LG B6 handles lower-quality material very well. This is largely thanks to effective digital image processing, which can mask some of the source’s imperfections without overly smoothing the whole scene. The "Smooth Gradation" function proves particularly useful. It noticeably reduces posterisation, especially in dark parts of the image. The safest choice remains the Low or Medium setting. The function still effectively smooths out unsightly tonal banding, but does not yet interfere too much with fine details. Purists can of course leave it switched off. Upscaling to 4K also performs very well. Full HD and 720p material retain a good amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations only become apparent with very poor sources below 720p, where the smallest text and fine elements are not always perfectly sharp, but this applies to almost every other TV on the market.

Philips PUS8359 will not be the best television for sports. The reason for this is the lack of implementation of even the basic motion smoothing feature, which was to be expected given the price of the device. We also note that we are dealing with a VA panel, whose sharpness is not of the highest standard. This type of panel is mainly associated with high contrast, which goes hand in hand with quite a slow response time, as clearly indicated by the matrix analysis results. As you can see from the images captured in rapid motion, the picture is typically blurred for this type of panel. Although it may not be the ideal option, it can be used conditionally for watching sports; however, one must keep in mind the less than optimal sharpness in motion. It is worth mentioning that films will exhibit judder, as the television does not have any motion smoother, even the simplest one.

One of the biggest advantages of OLED panels is the very fast pixel response time. This keeps the picture sharp and free of the visible smearing often seen on LCD TVs. However, there is a downside. During slow camera pans motion can look choppier than on LCD screens, where some of that effect is naturally masked by the slower panel. Fortunately, on the LG B6 this can be easily mitigated using the TruMotion system. With the motion smoothing set correctly you can achieve smoother motion without giving the picture an exaggerated soap opera effect.

It will not be a surprise if we write that Philips PUS8359/12 only offers the most basic support for consoles. Once the console is connected, we can count on features such as: VRR and ALLM. This is quite pleasing in the case of the former, as experience has shown that even in more expensive units there can be issues with this. A nice touch is the implementation of a special GameBar that allows for changing settings on the "fly," so we won't have to exit the game and unnecessarily distract ourselves. This feature also allows for adapting gameplay to the needs of people with disabilities, which will certainly be extremely useful.

LG OLED B6 has plenty to offer gamers; it’s simply a complete base for PS5, Xbox Series X/S or a capable PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can avoid irritating cable swapping when connecting several newer devices at once. It offers a full suite of synchronization technologies, from standard VRR to G-Sync and FreeSync. The screen synchronises the refresh rate seamlessly with the frame output from the console or graphics card. Of course it includes ALLM: the B6 automatically recognises when a game is running and immediately reduces latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG standard means that, after initial calibration in the console settings, the image won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on the cake is the Game Bar. Instead of digging through the full menu during gameplay, a single click is enough to adjust shadow visibility, tweak selected parameters or simply check the current display mode. All of this makes the LG B6 an excellent choice for gamers.
