Panasonic Z95A vs SAMSUNG S90F (WOLED)

Panasonic Z95A shows class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly reproduces details and the intensity of bright spots, making a strong impression with its power. In more demanding moments, like the final scene from The Meg, you can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic panels. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers great coverage of wide colour gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This means that colours are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colours look more realistic, and the HDR effect gains intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables such high luminance and excellent image detail. With it, the Panasonic Z95A offers HDR at a level that truly makes a difference.

Does the S90F handle not only blacks but also bright parts of the image? Definitely. The stories about OLEDs as "dark screens" can slowly be regarded as myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value more than enough to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, 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 card from the movie The Meg (photo 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be said 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.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. This mode offers quite good image reproduction, but it is not without certain flaws that need addressing. Primarily, the white balance, for both 4K and HD content, tends to be dominated by red and blue hues. This leads to a slight pink tint in the image, particularly noticeable in bright, white scenes. Such discrepancies can be seen in the comparative image below, which illustrates the issue well. The Colour Checker test also confirms these inaccuracies, showing slight shifts of dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor issues when brightening small details. A greater challenge arises with the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image overly bright, especially in more demanding scenes. While the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully harness the television's potential.

Samsung S90F, like most modern televisions, offers many picture modes, but – following our testing tradition – we checked it out in the best one, which is the Filmmaker mode. Thanks to this, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially dimmed – simply closer to what one should see. Of course, “more accurate” doesn’t mean “perfect”. Unfortunately, our S90F had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more “filmic” – because it’s warmer – but let’s not kid ourselves, George Lucas didn’t film Star Wars in sepia 😉 (you’ll find a comparison with the scene below as always).

Additionally, in HDR materials, there was an issue with brightness management. The EOTF curve showed a clear “spike” in brightness – the television brightened the image more than it should have, causing some effects to look too intense and deviating from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you’ll read about its effects later in the review.

After calibration, Panasonic Z95A showcases its full potential, delivering an almost perfect image. The television offers extensive adjustment capabilities, which we have fully utilised. The white balance post-calibration is absolutely flawless, and the errors in SDR content at 0.5 are at an exceptionally reference standard. The same goes for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and cinema-quality image enthusiasts. Significant changes have also occurred in the brightness characteristics – the EOTF curve has been aligned, eliminating previous issues with excessive brightness. Additionally, a small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it's in a completely different league. It's a true feast for the eyes, and the quality is hard to compare to anything else. Once fine-tuned, the Panasonic Z95A becomes a true master of colour reproduction.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older movies in SDR quality finally look like they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is back in place (no thanks needed, 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. Admittedly, the most demanding users may detect minimal deviations in brightness, but honestly – most viewers won't even notice that. And it's no surprise because the vast majority of errors fall below the ΔE 3 value, which is below the threshold of visibility. After calibration, the S90F (WOLED) becomes a truly excellent display – one on which you can enjoy nearly perfect image quality.

In the case of lower quality materials, the "Gradation Smoothing" function is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – while they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be evaluated as average, but sufficient for improving the quality of tonal transitions.

As for digital processing, or upscaling, the picture looks surprisingly good. It is flexible and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be observed, such as "aliasing" on edges, e.g. branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

Digital Image Processing in S90F:

Fortunately, Samsung, like in most of its models, manages to effectively tackle the unwanted posterisation effect in the S90F. The function responsible for this element is noise reduction, which does a pretty good job of smoothing tonal transitions and eliminating unnatural colour blending – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with trade-offs. In addition to improving gradation, it can also remove film grain or slightly soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you care about preserving the original texture of the material.

Image Scaling in S90F:

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

Panasonic Z95A, with a 144 Hz panel, offers excellent image smoothness. For movies, there is an "Intelligent Frame Creation" feature that allows for improved smoothness and reduction of blurring. Users have two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in fast-moving scenes. "Film Smoothness" – adds smoothness by creating additional frames between the originals, making motion appear more fluid and natural with the effect of "soap opera"

As a result, viewers can adjust the settings to their own preferences. Movies and less dynamic content look smooth and natural, which should satisfy most users.

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 smooth, clear, and there’s no room for ghosting or blurring, which can sometimes plague cheaper LCDs.

The TV also comes equipped with motion smoothness settings that allow you to customise everything to your liking. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to the point of looking a bit soap opera-like), or more cinematic, with the classic “jumpiness” of 24 frames. The choice is yours, Samsung imposes nothing.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in support for gamers. The television offers practically everything you can expect from a device in this range. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a big plus for gamers using various configurations.

Also noteworthy is the unique and rather specific "Game Bar." Its bubble interface stands out from the competition and allows quick adjustment of key settings such as VRR, brightness level, or picture mode, without the need to interrupt gameplay.

However, in this class of devices, there has been a slight disappointment – Panasonic Z95A only offers two HDMI 2.1 ports instead of four. This is definitely too few for a premium television, especially in times when many people have more than one device requiring full HDMI 2.1 support, such as a next-gen console or a high-end computer. In this category, it's hard to accept, especially given the high aspirations of this model. Despite this, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.

When it comes to gaming features – the S90F has absolutely nothing to complain about. 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 Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus deserves special mention – Samsung's proprietary motion smoother that actually works sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It's also worth mentioning the HGiG feature, which – and this may be a slight surprise – works correctly. We bring this up because Samsung clearly messed something up in one of the recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes almost 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 new software versions and information from the manufacturer.
