Philips PUS8209 vs Samsung S90H (WOLED)

Unfortunately, this is where the problems start. A maximum brightness of 280 nits is definitely too low to experience the true effect of HDR. In practice, the image resembles standard SDR more, so it's hard to talk about deeper visual experiences. On the plus side, the colour gamut coverage is 91.4% DCI-P3, which will be sufficient for most films. It's also worth noting that the image is stable and there are no issues with sudden brightness or colour changes. Overall, HDR on this television is more of a formality than an actual added value. If we're looking for genuine HDR emotions, this model may not meet expectations.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although it is slightly dimmer compared with the QD-OLED version. That difference is not as pronounced as in last year’s F series, where gaps sometimes reached 500 nits. Here the parameters of both panels are very similar, with differences in peak brightness of only about 100–150 nits. In small-window measurements the S90H with the WOLED panel easily reaches close to 1,500 nits. That headroom lets it phenomenally convey the dynamics of HDR effects — blooms, light reflections and explosions have the right punch, exactly as intended by the studio creators. As with most OLED displays, when a very bright scene fills the entire screen, panel protection systems kick in and brightness naturally falls to around 700 nits. It’s worth stressing 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 stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, very high-brightness colours don’t achieve quite the same saturation, and the wide-colour volume is slightly more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches almost 99%, meaning that for the vast majority of real film scenes both variants will present an almost identical image. The real gap only appears in rarer, especially demanding productions that use the ultra-wide BT.2020 gamut. Because of the WOLED panel’s construction, coverage of that standard is roughly 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit HDR colours may appear a touch 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 distinct problems. For HD content, the white balance is characterised by a strong dominance of red, causing the image to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in mid-tones, has serious issues at the beginning and end of the graph. Drops in shadows result in a loss of detail in dark areas, and spikes in bright areas make some elements look unnatural.

For high-quality content in 4K HDR, the situation reverses. In this case, blue dominates, leading to an artificial image boost effect, reminiscent of unnatural retail settings. Such an image looks unappealing and does not align with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference graph, causing the image to appear too dark, stripping depth and detail from HDR content.

Against this backdrop, the errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively affects the overall image quality. The Filmmaker mode, while the best among those available, requires substantial corrections to truly convey the full vision of the director.

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 annoying oversaturation seen in more aggressive profiles. However, as is often the case without full calibration, there is unit-to-unit variation. In our test the white balance was a little deficient in the blue component, so the image leaned slightly 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 around 2.2, which caused a small lift in shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

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

After full calibration, you can safely say the S90H in the WOLED version looks almost perfect. In SDR mode colour errors fall to ultra-low levels and Delta E values very rarely exceed 2. That's a phenomenal result, so if perfectly faithful colour reproduction matters to you, it's definitely worth getting it calibrated. The calibrated HDR mode also performs very well, where the white balance was stabilised and previous deviations eliminated. After professional tuning it's really hard to fault anything, because the TV delivers an image with almost exemplary naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the saturation limitation in extremely bright scenes, while the tuning potential and colour fidelity are at the highest level.

The television offers a “Distortion Reduction” feature that effectively improves the gradation of tonal transitions, particularly when set to the minimum level. Unfortunately, this comes at a cost – the feature also smooths out details like material textures. On the plus side, it’s worth noting that the operation of this option does not negatively affect the 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, issues with aliasing of certain elements, such as branches or small details, can sometimes be noticed, which may decrease the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

When it comes to banding reduction itself, Samsung has kept the same solutions known from last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that’s somewhat more prone to banding. However, it’s important to remember it acts aggressively. This mechanism, aside from the artefacts themselves, can remove fine film grain and subtly soften detail. Ultimately it’s a trade-off, but if you want perfectly faithful image reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so upscaling quality was almost identical. The chip sharpens lower-resolution material very well, pulling a satisfying level of detail out of it. However, Samsung still hasn’t solved the old overscan problem. For some older recordings or archival footage the edges of the image can be slightly cropped. It’s a minor drawback, but it’s a shame the manufacturer still hasn’t fixed it.

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but here you can also feel a certain shortcoming. The television does not offer any motion smoothing that would allow you to adjust the fluidity of the picture to individual preferences, which for some users may be disappointing.

When it comes to motion handling the S90H is simply excellent. This year's panel offers its refresh rate boosted to 165 Hz, although in practice the benefit will mainly be for gamers connecting a powerful PC. For movies, TV 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, the OLED panel's lightning-fast response time does the job. Motion is clean, and the ghosting or smearing seen on LCDs simply doesn't occur here.

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

Unfortunately, due to the 60 Hz panel, the TV will not meet the expectations of more demanding gamers who are looking for higher fluidity and precision of image. 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.

Gamers should feel right at home with the S90H, because Samsung has left few reasons to complain in this area. The TV has four HDMI 2.1 ports, each supporting 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. In last year's models it could cause issues when used with a console, but on the S90H it now works as it should. What really stands out against the competition is Game Motion Plus. It's a specialised motion-smoothing mode for games that works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother and 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 big 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 the more useful feature.
