Philips PUS8209 vs SAMSUNG S90F (WOLED)

Unfortunately, this is where the problems begin. A maximum brightness of 280 nits is definitely too low to feel the true effect of HDR. In practice, the image resembles standard SDR more, so it’s hard to speak of deeper visual experiences. On the positive side, the colour gamut coverage is commendable – 91.4% DCI-P3 is a score that will be sufficient for most films. It must also be said that the image is stable and there are no issues with sudden changes in brightness or colours. Overall, HDR on this television is more of a formality than an actual added value. If we are looking for genuine HDR thrills, this model may not meet expectations.

Does the S90F handle not only black, but also bright parts of the image? Definitely yes. Tales of OLEDs as “dark screens” can slowly be regarded as a myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value entirely sufficient to enjoy impressive and dynamic HDR imagery – both in films and series. Most of the scenes we tested look superb, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test pattern from the film The Meg (picture 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be considered that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

Philips PUS8209 offers many picture modes, but the best of them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its clear problems. In the case of HD content, the white balance is characterised by a strong dominance of red, which causes the picture to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in the mid-tones, has serious issues at the beginning and end of the curve. Drops in the shadows cause a loss of detail in the dark areas, and blowouts in the bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an artificial enhancement effect, reminiscent of unnatural retail settings. Such an image looks unattractive and inconsistent with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference chart, causing the image to appear too dark, robbing the depth and detail of HDR content.

Against this backdrop, errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively impacts the overall image quality. The Filmmaker mode, although the best among the available options, requires substantial corrections to fully convey the director's vision.

The Samsung S90F, like most modern televisions, offers many picture modes, but – in line with our testing tradition – we assessed it in the best one, which is the Filmmaker mode. This way, the image looks significantly more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially muted – just closer to what should be seen. Of course, "more correct" does not mean "ideal". Unfortunately, our S90F unit had considerable issues with white balance, especially in the blue range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more "cinematic" – because it is warmer – but let's not kid ourselves, George Lucas did not film Star Wars in sepia 😉 (you will find the comparison with the scene as always below).

Additionally, in HDR materials, there was a noticeable issue with brightness management. The EOTF curve showed a clear "spike" in brightness – the television brightened the image more than it should have, which made some effects look overly intense and diverged from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you will read about its effects later in the review.

After calibration, the white balance for HD and 4K content has significantly improved. Although we have not achieved a perfectly flat characteristic, the effect is definitely better than before. The picture on the television no longer appears artificially warm or excessively cold, which significantly enhances the naturalness of the displayed content. The brightness characteristic (gamma) has also been adjusted – the biggest issues at the beginning and end of the graph have been mitigated. The EOTF curve, responsible for brightness in 4K HDR material, has been stabilised, eliminating problems with excessive dimming of the image. In the colour palette test, some imperfections can still be noticed due to average coverage of the wide colour gamut, which is a limitation of the equipment itself. Nevertheless, the final effect is clearly better than before calibration – the image looks more natural and approaches the expectations of the Filmmaker mode.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older films in SDR quality finally look as they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics returns to its rightful place (you’re welcome, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Yes, the most demanding users may spot minimal deviations in brightness, but honestly – most viewers won’t even notice that. And it's no wonder, because the vast majority of errors are below a ΔE value of 3, which is below the threshold of visibility. After calibration, the S90F (WOLED) truly becomes an excellent display – one that provides nearly perfect picture quality.

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, this comes at a cost – the feature simultaneously smooths out details such as the texture of materials. On the positive side, it is worth noting that the operation of this option does not negatively affect film grain, which remains intact.

As for image scaling (upscaling), the television generates a plastic, soft image that generally looks pleasant. However, in the background, one can sometimes notice issues with aliasing on certain elements, such as branches or fine details, which can lower the quality of reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

Digital Image Processing in the S90F:

Fortunately, Samsung, as in most of its models, effectively manages the unwanted posterisation effect in the S90F. The feature responsible for this aspect is noise reduction, which does a decent job of smoothing tonal transitions and eliminating unnatural colour connections – of course, within its limitations. Unfortunately, it operates rather aggressively, so using it comes with compromises. In addition to improving gradation, it can also remove film grain or gently soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you want to preserve the original texture of the material?

Image Scaling in the S90F:

In this year's model, Samsung implemented its own AI processor – NQ4 Gen3, which does quite well with upscaling. In our test scenes, the television effectively "pulled up" lower quality towards artificial 4K – the image was more pleasant to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing facade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival materials – e.g. a VHS tape of your parents' wedding – you must expect that the lower part of the image may be cut off. The image adaptation function to resolution simply does not work here as it should.

The 60 Hz panel in the Philips PUS8209 is mainly suitable for watching films, but there is still a sense of something missing. The television does not offer any motion smoother that would allow users to adjust the fluidity of the picture to their individual preferences, which can be disappointing for some users.

The S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is fluid, clear, and there’s no room for any ghosting or blurring that sometimes plagues cheaper LCDs.

The television is also equipped with motion smoothness settings, allowing you to customise everything to your preference. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to that soap opera effect), or more cinematic, with the classic 24-frame 'choppiness'. The choice is yours; Samsung doesn’t impose anything.

The Philips PUS8209 offers basic features useful for gamers, such as variable refresh rate (VRR), automatic low latency mode (ALLM), and a Game Bar that makes managing settings easier.

Unfortunately, due to the 60 Hz panel, the television will not meet the expectations of more demanding gamers who are counting on higher smoothness and image precision. Additionally, this model does not support any HDR mode dedicated to gaming, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.

When it comes to gaming features – the S90F has absolutely nothing to fault. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find the Game Bar – a practical tool that allows you to quickly glance at picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus also deserves a mention – Samsung's proprietary motion enhancer that is the only one truly functioning sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It is also worth mentioning the HGiG feature, which – much to our slight surprise – works correctly. We're mentioning this because Samsung clearly broke something in one of the last updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes practically impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for updates and information from the manufacturer.
