Philips PUS8209 vs Samsung S90H (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.

Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although compared with the QD-OLED version it is slightly dimmer. The difference is not as significant as in last year’s F series, where the gap could reach as much as 500 nits. Here the parameters of both panels are very similar, and differences in peak brightness are only in the order of 100–150 nits. In small-area measurements the S90H on the WOLED panel easily reaches levels close to 1500 nits. Such a reserve of power allows HDR dynamics to be reproduced phenomenally; all highlights, light reflections and explosions have the necessary punch, exactly as the creators intended in the editing studio. As with most OLED displays, when a very bright scene fills the whole screen protection systems activate and brightness naturally falls to around 700 nits. It is worth emphasising that this is still an excellent result on the market. Often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This results directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a consequence, colours at very high brightness do not reach the same intense saturation, and the volume of the wide gamut is somewhat more limited than in QD-OLED. That does not change the fact that in everyday use these differences will be hard for most viewers to spot. The DCI-P3 space we measured reaches nearly 99% on the WOLED panel, which means that in the vast majority of real film scenes both variants will present an almost identical picture. The true distance only reveals itself in rarer, exceptionally demanding productions that use the ultra-wide BT.2020 gamut. Due to the specifics of the WOLED panel’s construction, coverage of that standard is about 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit colours in HDR may appear slightly less vivid.

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.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the irritating oversaturation found in more aggressive presets. However, as is often the case without full calibration, no two units are identical. In our test the white balance was slightly lacking in blue, causing the image to lean a little towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at 2.2, which produced a minor lift in shadow detail. In HDR mode the tuning was somewhat better, showing only a slight undersaturation in the red region.

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 a full calibration it’s fair to say the S90H in WOLED guise looks almost perfect. In SDR mode colour inaccuracies drop to ultra-low levels and Delta E values very rarely exceed 2. That’s a phenomenal result, so if you care about perfectly faithful colour reproduction it’s definitely worth considering calibration. The calibrated HDR mode also performs very well, with the white balance stabilised and earlier deviations eliminated. After professional fine-tuning it’s really hard to find anything to criticise, because the TV delivers an image with almost reference-level naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the aforementioned limitation in saturation in extremely bright scenes; the tuning options and colour fidelity themselves are at the highest level.

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.

In terms of posterisation reduction itself, Samsung has kept the solutions known from last year’s models. The dedicated gradient-smoothing function performs quite well and can effectively mask unwanted tonal banding, which is useful on a WOLED panel that is slightly more prone to banding. However, you should be aware of its aggressive behaviour. This mechanism, alongside the artefacts themselves, can clean up fine film grain and gently soften detail. Ultimately it is a matter of compromise, but if you want an absolutely faithful reproduction, it is safer to leave this option off.

Similarly, in the area of scaling it is difficult to call this a breakthrough. The S90H uses the same NQ4 Gen3 processor as its predecessor, so the upscaling quality was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still has not dealt with the longstanding overscan issue, though. With some older recordings or archive footage the edges of the image can be slightly cropped. It’s a minor flaw, but it’s a pity the manufacturer still hasn’t eliminated it.

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.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a boosted refresh rate of up to 165 Hz, though in practice the benefit will mainly be for gamers connecting a high-end PC. For films, series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, however, the OLED panel's lightning-fast response time does its job, so motion is clean and the ghosting or smearing familiar from LCD screens simply does not occur here.

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.

Players should feel at home with the S90H, because Samsung has left few reasons to complain in that respect. The TV has four HDMI 2.1 ports, each of which supports VRR, ALLM and high refresh rates. There’s also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG mode. In last year’s models it could cause problems when used with a console, but on the S90H it now works as it should. What really stands out against the competition is the Game Motion Plus feature. It’s a special motion smoothing mode for games that works best with titles running at 30 or 60 fps. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That’s important, because on many TVs enabling a similar smoothing feature causes such a large increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There’s still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be a much more useful feature.
