Panasonic Z95B vs Philips OLED811

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.

Philips OLED811 uses the new generation WOLED EX panels, also found in models like the LG C6 and Samsung S90H. After calibration we measured around 1500 nits, which is a very good result for an OLED TV. You can see it clearly in movies and series. All kinds of light flashes have the right intensity, especially when they appear on a dark background. In such scenes the OLED811 can deliver truly impressive HDR. Of course, that doesn't mean you'll see that peak brightness in every shot. When the screen is filled with a large area of white or a big explosion, brightness falls to around 600 nits. That's still a good result, but those scenes no longer have the same punch as small, bright elements on a dark background. This is a known limitation of OLEDs, and the OLED811 is no exception.

Colors

Aside from HDR brightness, colors also matter, and Philips performs very well here too. It covers almost the entire DCI-P3 gamut, which contains most of the colors used in HDR movies and series. So you get rich reds and lush greens, and while watching it's hard to find major faults in this area. It looks a bit worse with the much wider BT.2020 gamut — its most saturated shades are already beyond the reach of this panel. Added to that is the issue of the white subpixel the WOLED panel uses to help boost brightness. With very bright colors you can see some "whitening": the color is bright but loses some of its saturation. In exactly these situations QD-OLED panels from Samsung Display have the advantage. In most movies and series, however, this won't be something that immediately stands out.

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.

The movie mode on the Philips OLED811 is sensibly configured right out of the box. Most color errors are minor, both in SDR and HDR, so you can sit down and watch without first adjusting the settings. There are no major inaccuracies that would immediately pull attention away from the film.

It's not perfect, though. The white balance shows a slight deficiency of red compared with green, so whites and grays can have a faint greenish tint. It's not a strong cast, but measurements clearly show it. There are also small brightness deviations in SDR: some areas of the picture are slightly lifted, and the deepest blacks aren't always rendered evenly. In HDR the TV tracks the reference much more closely, although in places it slightly pulls details out of the shadows. These are generally things to refine. The factory movie mode provides a good starting point, and calibration will show how much more you can get out of it.

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.

After calibration the Philips OLED811 produces an image very close to the reference. We managed to even out the white balance and remove the subtle color cast visible in the factory settings. Errors in Color Checker measurements for SDR and HDR dropped to around 1 to 2, and many samples even fall below 1. That's a level at which it's hard to spot differences from the reference image with the naked eye. We also improved the gamma, and only in the brightest whites a slight brightening remains. In HDR the EOTF curve also stays close to the reference, although the TV still tends to slightly boost the brightness of small elements like stars or subtitles. That gives the image a bit of extra glow that shouldn't be there, but otherwise there's little to complain about. It was already good out of the box, and after calibration we managed to refine most of the remaining shortcomings.

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 OLED811 handles lower-quality content reasonably well, though it's far from perfect. The "Artifact Reduction" feature helps smooth tonal transitions and on the low setting delivers a pretty good result. It doesn't remove banding between shades as effectively as similar solutions from some competitors, but at least it doesn't introduce new artifacts. That's a sensible setting for everyday viewing. Still, there's some disappointment, because the MediaTek Pentonic 800 chip used here can, in other manufacturers' implementations, deal more effectively with heavy compression even at similarly low settings. A lot therefore depends on how each manufacturer uses its capabilities. We have a few more reservations about the 4K upscaling itself. There is plenty of detail, but the overall image looks fairly soft. Edges are heavily smoothed, which robs the picture of some sharpness and clarity. You can partly correct that with the sharpness slider in the menu, though that will just emphasize outlines rather than recover detail. On the plus side, there is no overscan, so even with an SD signal the TV does not crop the edges of the picture.

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.

In terms of motion handling, the OLED811 performs excellently. At 120 Hz, which is useful for console gaming and watching sports, the image stays clear and moving objects don’t leave noticeable trails. The fast response of OLED pixels helps here; you can see it clearly in the UFO test, even on dark backgrounds. There are also motion-smoothing controls. For movies you can adjust the strength of smoothing to your taste, ranging from preserving a cinematic feel to much smoother motion. A separate motion blur reduction control is useful for fast-paced content like live sports broadcasts.

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.

OLED811 has almost everything you could expect from a gaming TV. It supports 120 Hz at Full HD, 1440p and 4K resolutions, and when connected to a PC can reach 165 Hz. It also has VRR, which helps avoid screen tearing with variable frame rates, and ALLM, which automatically switches to game mode. So you don't have to dig into the settings every time you power up your console.

HGiG also works correctly, so once you enable HDR on the console the TV doesn't apply its own brightness adjustments. There's also a Game Bar that lets you check signal parameters and quickly change settings useful while gaming. The list even includes Dolby Vision for games, but there's a significant catch, which you'll read about below.
