Panasonic Z95B vs Dreame S100

The quality of HDR on the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, referred to by the manufacturer as Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in cinematic scenes. The effect is impressive and can amaze with the intensity of the light, providing a sense of connection with the screen that goes beyond previous experiences. Similar feelings 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 concerns full-screen bright sequences, such as the closing credits in the film The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an incredibly impressive result. One can thus say that HDR in this model has reached masterful form. A significant step forward is also evident in colour reproduction. 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 decreased. When watching films, the differences are subtle enough that under normal conditions they are hard to notice, and the colours remain vivid and saturated.

The Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached around 600 nits. This is a really good result, although not the highest when considering the competition at this price point. In fullscreen scenes, it is evident that the television can produce an image that impresses with its brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model primarily focused on maintaining the deepest blacks. However, this came at the expense of HDR performance – and in a drastic manner. In such scenes, the brightness of bright elements dropped below 100 nits, which is a frankly tragic result, far from any HDR effect. One can improve this aspect, but not without a "however." It is simply necessary to change the local dimming setting in the television's menu, but then the blacks in such scenes simply become grey. It's a pity that Dreame couldn't better refine the local dimming algorithms, and the S100 is another example that the sheer number of local dimming zones does not always translate to a better image. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" type television, although in reality it uses a PFS LED filter. As a result, the colours are appropriately saturated, and the colour gamut coverage of DCI-P3 we measured exceeded 94%.

The factory colour reproduction of the Filmmaker mode, my dear friends, is truly remarkable in the case of the Panasonic Z95B. I'm referring to our test sample, but the result was so good that it’s hard to believe. The only detail one might nitpick about is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image unlike anything we have ever seen in factory mode. Tests of the colour palette, Color Checker – everything indicated values below Delta 2. That’s a much lower result than the threshold of human eye perception, which means, quite simply, that the viewer has no chance of noticing any serious deviations. It looks as though Panasonic has actually calibrated this model at the factory stage. Of course, we cannot rule out the possibility that we received an exceptionally well-set sample, but the result is still impressive. We are very strict when it comes to evaluating factory calibration, and here our jaws simply dropped.

We tested the Dreame S100 in 'movie' mode and we definitely recommend using this setting for watching all types of content. Interestingly, within the deeper settings of the television, we also find a dedicated 'Filmmaker' mode, which is now available from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all settings related to the picture and does not allow for any configuration in the menu - even motion smoothing. So, how do the factory colours of the S100 fare? Not too badly, but also not the best. The television itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This made the picture artificially brightened, and the colours had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how the colour samples tend to drift towards blue, generating quite significant colour errors. The picture in HDR mode looked definitely better, where the colour errors were not as prominent, although they still fell far from perfection. Here, the white balance was also shifted too much towards blue, causing considerable errors in colour reproduction.

The colour representation after calibration in the Z95B is a topic that is difficult to elaborate on, as there was simply not much to be done here. A slight adjustment of the white balance was sufficient to eliminate the lack of blue, and at this point, the picture reached an almost reference level. It must be admitted that we haven't had such a small range of work in a while. If any of you are particularly observant, you may notice minimal deviations in the EOTF curve, but this is rather related to the operation of the dynamic tone mapping function we mentioned earlier. In fact, it is not a flaw, but a characteristic of this solution, which deliberately alters the brightness characteristics depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great straight out of the box, and after calibration, it reaches a level where it is truly difficult for us to find anything to improve.

The Dreame S100 has proven to be a device very amenable to professional calibration. In its menu, we found a plethora of advanced options that allowed us to effectively correct factory errors. Thanks to advanced white balance correction – both in SDR and HDR content – we completely eliminated the excess blue components. The image immediately became much more natural and pleasant to the eye. After fully tuning the colours, the errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any colour distortions have become nearly impossible to perceive with the naked eye. This is truly a pleasant surprise, as new brands in the television market often encounter significant issues with the correct implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we must criticise is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, anomalies can be seen on the EOTF curve we measured. Where high highlights should appear, there is a slight boosting of the curve above the reference line. In practice, this causes an unnatural brightening of some of the brightest elements in films or games. Despite this minor flaw, professional calibration brings about a huge, very positive change in this model.

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

The situation with digital processing is less impressive. Features such as “gradation smoothing” or “block noise reduction” practically do not work – the material tested looked identical regardless of the settings. We might as well state that this feature simply does not exist. This is somewhat disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence to enhance picture quality. Meanwhile, in such a basic area, the television does not provide a real effect and it appears weaker than one might expect from high-end equipment.

For scaling and digital processing in the Dreame S100, the technology that the manufacturer proudly calls Dreamind™ Pro AI is responsible. However, it must be clearly stated that this is not a proprietary processor, but merely a marketing name for a chip made by MediaTek – more precisely, the MT5889 model. Unfortunately, we are talking about a rather outdated unit, from a time when MediaTek lagged significantly behind the competition in terms of performance. This unfortunately has a direct impact on the image as that is what this chip also deals with. The upscaling in the S100 is quite mediocre, and the processor has a tendency to heavily and artificially sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find the "Contour Smoothing" feature, which theoretically is supposed to improve tonal transitions. In practice, it offers almost no improvement – setting it to any level rarely eliminates visible banding of colours, but it can unnecessarily blur elements of the image that should remain sharp.

A separate issue is the phenomenon of overscan (cropping the edges of the frame), which is noticeable here practically all the time. Although there is an option to set the screen to display the full frame in low-resolution materials, this requires activating the previously mentioned Filmmaker mode. And as you know, this mode completely blocks the adjustment of any other sliders in the picture menu. In our test tables, we marked that the television offers an option to disable overscan, as technically such a function exists in the system – however, in everyday use, when maintaining sensible image settings, you will not be able to take advantage of it.

The OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It is also very important that the television is equipped with an proprietary motion smoothing system called “Intelligent Frame Creation”. Among the available sliders, the most important one is the one named “film smoothness”, as it allows you to adjust motion to your own preferences when watching 24-frame materials, i.e. films – from a more “frame-like” appearance to a smooth, almost theatrical effect. It is somewhat disappointing that Panasonic did not choose to overclock the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know that the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so in everyday viewing, it is not a significant drawback since we are limited to 120Hz.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a refresh rate of 144 Hz, although in reality, the vast majority of people using it in a traditional way will still be limited to 120 Hz (as this is the maximum supported by today's equipment apart from PCs). Thanks to the high refresh rate, the image in motion remains really sharp, largely thanks to the well-functioning MEMC smoother. In the menu, we find predefined modes that allow the television to efficiently generate artificial frames, which effectively improves the fluidity of dynamic sports scenes, but also eliminates image stuttering in film and series materials recorded at 24 frames.

The Panasonic Z95B is fully equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you would expect from a modern screen. There is VRR frame synchronization, an automatic ALLM game mode, and full compatibility with HDR formats used in games. The television 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 room here for features for gamers. On board, there is a Game Bar (or rather Game Circles) – visually, it looks a bit unusual, but it serves its purpose and allows you to quickly check the most important picture parameters. The only thing that is actually missing for complete happiness is having four HDMI 2.1 ports instead of two. It's a minor detail, but in a television of this class, one could expect a full set.

The Dreame S100 seems almost like the perfect screen for a gamer. The television is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that functions like automatic game mode (ALLM) and variable refresh rate (VRR) ranging from 48 to 144 Hz work seamlessly on consoles. It also features a well-designed gaming panel (Game Bar), allowing users to continuously monitor important parameters—from active picture modes to the number of frames rendered by the console, and even the option to add a crosshair in the middle of the screen. All of this looks great on paper; however, the biggest problem with the S100 is the implementation of HDR mode in games. The television does not have the HGiG format implemented correctly. As a result, an unsuspecting user may incorrectly configure the console when first using the screen. Poor configuration can lead to an image that is too dark or too washed out (as a guideline: we suggest setting the brightness in the Xbox console menu to around 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format also proves problematic, as it often would not activate at all between the XBOX and Dreame S100. And when it was finally managed to be activated, playing was not possible due to a very high input lag often exceeding 100ms. If the manufacturer can improve the HDR issue in games via an update, the S100 will be truly excellent hardware for gamers. For now, however, compromises need to be accepted.
