Panasonic Z95B vs Samsung OLED S90F (QD-OLED)

The quality of HDR in the Panasonic Z95B belongs to the absolute elite. Thanks to the latest generation panel, named by the manufacturer Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in movie scenes. The effect is impressive and can amaze with the intensity of light, giving a sense of contact with the screen that goes beyond previous experiences. Similar sensations accompanied us only during tests of the LG G5, Samsung S95F, or Philips OLED910. Of course, there are moments when the device's algorithms decide to limit luminance – this especially applies to full-screen bright sequences, such as the closing credits in the movie The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still a result that makes a huge impression. One can say that HDR in this model has been brought to a masterful form. A significant step forward is also visible in the reproduction of the color palette. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of full gamut coverage, but the gap between these solutions has significantly narrowed. When watching movies, the differences are subtle enough that it's hard to notice them under normal conditions, and the colors remain vivid and saturated.

The biggest difference between the 65-inch S90F and the other versions is brightness. The QD-OLED panel can achieve up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with the WOLED panel. This translates to a significantly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we have to admit we were pleasantly surprised because we expected results closer to the WOLED version, but we got an effect that makes a big impression even in movies. As with any OLED, there are moments when the panel has to limit brightness somewhat. This mainly concerns full-screen, very demanding scenes – for example, in the last test frame from the movie "The Meg," brightness drops to around 800 nits. However, it's hard to consider this a flaw since it’s still an excellent result, unprecedented in OLED TVs in this price range. All signs indicate that the 65-inch S90F could be one of the best choices this year for those looking for a strong OLED at a reasonable price. Another advantage of the QD-OLED panel in HDR content is its color gamut coverage. Thanks to quantum dots, the television achieves almost full 100% of the DCI-P3 color gamut and nearly 90% of the BT.2020 gamut. These values place it alongside much more expensive models and make it exceptional in its class.

The factory color reproduction in Filmmaker mode, my friends, is a true phenomenon in the case of the Panasonic Z95B. I'm talking about our test unit, but the result was so good that it's hard to believe. The only detail to nitpick is a slight lack of blue in the white balance, but other than that, the television, right out of the box, displayed an image like we've never seen in factory mode. Color palette tests, Color Checker – everything pointed to values below Delta 2. This is a much lower result than the threshold of human eye perception, which means, quite frankly, that the viewer stands no chance of noticing serious deviations. It looks as if Panasonic really calibrated this model at the factory stage. Of course, we cannot rule out that we got an exceptionally well-set unit, but the result is still impressive. We are very strict in our assessments of factory calibration, and here our jaws simply dropped.

Samsung S90F, like most modern televisions, offers several picture modes, but in keeping with our tradition, we checked it in the most important one, which is Filmmaker. This setting makes the picture look much more natural than in the default, often oversaturated modes. It is neither overly saturated nor artificially subdued – just closer to what you should actually see. However, that doesn't mean it's perfect. The S90F had noticeable shortcomings in white balance, primarily in the blue range, which created a slightly yellowish filter effect on most scenes. One might argue that it looks more "cinematic" because it's warmer, but let's not kid ourselves – George Lucas didn't shoot Star Wars in sepia 😉 (you'll find a comparison with a scene below as always). In HDR materials, there was also a problem with brightness management. The EOTF curve clearly showed that the television brightens the picture more than it should, which led to some effects looking too intense and deviating from the reference. Fortunately, many of these shortcomings can be eliminated through professional calibration – we will discuss the effects of this procedure further in the test.

The color reproduction after calibration in the Z95B is a topic that is difficult to elaborate on for long because there simply wasn't much to be done here. A slight adjustment of the white balance was enough to eliminate the lack of blue, and at that moment the picture jumped to an almost reference level. I must admit that we haven't had such a small scope of work in a long time. If any of you are particularly observant, you might notice minimal deviations in the EOTF curve, but this is more related to the operation of the dynamic tone mapping function that we mentioned earlier. Really, this is not a flaw, but rather a feature of this solution, which intentionally changes the brightness characteristic depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that already looks great right out of the box, and after calibration, it reaches a level where it is really hard for us to find anything to improve.

Calibration quickly showed that the S90F has a substantial reserve of capabilities. The image in SDR immediately gained a natural quality – classic films stopped looking as if someone had applied a yellowish filter to them, and the colors regained their true character. It’s a return to the atmosphere of the original, without the impression that someone tried to "age" it artificially. In HDR content, the difference was even more pronounced. The EOTF curve was managed almost to a reference level, and any deviations are so subtle that most viewers won't even notice them. In practice, the S90F after calibration displays an image very close to perfection. Compared to the WOLED version, it performs even better – mainly due to the wider color gamut coverage, which makes the colors look fuller and more vibrant.

Let's start with what works well. The upscaling in the Z95B is at a very high level – the picture in lower resolutions is clear and sharp, with only minor drawbacks being slight aliasing in some areas of the image. It's also important that the television does not crop the material in any way and maintains its aspect ratio, which is not always an obvious fact even in 2025.

The situation is worse when it comes to digital processing. Features such as "gradation smoothing" or "block noise reduction" practically do not work – the tested material looked identical regardless of the settings. We might as well point out that this function simply doesn't exist. This is somewhat disappointing, especially since Panasonic strongly promotes its HCX Pro AI II processor, boasting of the presence of artificial intelligence that improves picture quality. Meanwhile, in such a basic matter, the television does not deliver a real effect and looks worse than one might expect from top-of-the-line equipment.

The S90F performs really well here, although there are some comments that are repeated in the case of most Samsung TVs. The noise reduction feature can effectively smooth out unwanted color transitions in lower-quality materials, such as television or YouTube, making them simply look better. However, it should be noted that it operates quite aggressively and can also soften elements that we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to use it in the "medium" setting and be aware of the compromise it brings. The upscaling itself is at a high level – low-quality materials are enhanced towards a 4K-like image. The only caveat is that the S90F can still have problems with so-called overscan, which is slight trimming of the edges in very poor materials like 576p and lower.

The OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as soccer or basketball matches, and the Z95B is no exception. It's also very important that the television is equipped with the proprietary image smoothing system "Intelligent Frame Creation." Among the available sliders, the most important one turns out to be the one named "film smoothness," because it allows adjusting the motion to personal preferences when watching 24-frame material, that is, movies – from a more "frame-like" appearance to a smooth, almost theatrical effect. It's a bit of a shame that Panasonic did not choose to push the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so for everyday viewing this is not a significant drawback as we are limited to 120Hz.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, what matters most is how it performs at 120 Hz, as this frequency is the most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels—the pixel response is almost instantaneous, allowing motion to be rendered with surgical precision. The effect is easy to predict. The image is practically free of ghosting, making gaming on consoles, matches, or other sports broadcasts a great pleasure on the S90F.

Fans of movies and series are not forgotten either. Like every Samsung TV with a refresh rate of 120 Hz and above, the S90F is equipped with a proprietary motion smoother called "Image Clarity." Here, we find two sliders—motion blur reduction and judder reduction—that allow you to improve the fluidity of materials recorded at 24 frames and adjust the effect to your personal preferences.

The Panasonic Z95B is completely equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you can expect from a modern screen. There is VRR frame synchronization, an automatic game mode (ALLM), and full compatibility with HDR formats used in games. The TV supports both Dolby Vision for Xbox and the popular HGiG, which has been implemented correctly in this case, so it actually works as it should.

Although the brand is mainly associated with home cinema and equipment for filmmakers, there is also a place here for conveniences for gamers. It comes with Game Bar (or rather Game Circles) – visually it looks a bit unusual, but it does its job and allows you to quickly check the most important image parameters. What it really lacks for complete happiness is actually just four HDMI 2.1 ports instead of two. It's a minor issue, but one would expect a full set in a TV of this class.

S90F is a television that truly brings a lot of joy when gaming. Right off the bat, we get four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without having to figure out which device takes priority. This is a convenient and practical solution that is not a given with other manufacturers. Additionally, there are key features such as the automatic game mode (ALLM), which switches the screen to low-latency settings, and VRR frame synchronization working over a wide range from 48 to 144 Hz. This ensures that the picture remains smooth regardless of whether we are playing fast-paced online shooters or calmer story-driven titles. Another noteworthy feature is the Game Bar – a panel that allows quick access to several useful additions. For example, you can turn on an additional crosshair in the center of the screen, enlarge the minimap, or, in the case of a PC, change the aspect ratio. Finally, there is also the unique Game Motion Plus mode exclusive to Samsung. Its purpose is to smooth out older or less optimized titles, and it actually works quite well. Thanks to this mode, even less polished games can look better and provide more enjoyment than on other televisions that theoretically offer the same technical specifications.
