Panasonic Z95B vs LG OLED B6

The HDR effect quality in the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, named Primary RGB Tandem OLED by the manufacturer, the television can achieve over 2000 nits of brightness in movie scenes. The effect is impressive and can amaze with its intensity of light, giving a sense of contact with the screen that goes beyond previous experiences. Similar feelings were only experienced 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 ending credits in the movie The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an extremely impressive result. Thus, it can be said that HDR in this model has been brought to a masterful form. A significant step forward is also visible in the reproduction of the colour palette. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of gamut coverage, but the gap between these solutions has significantly decreased. When watching films, the differences are subtle enough that under normal conditions it's hard to notice them, and the colours remain vibrant and saturated.

LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year's B5. That's down to LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD-OLED panels. This is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

The factory colour reproduction in Filmmaker mode, my dear friends, is a true phenomenon in the case of the Panasonic Z95B. I'm talking about our test sample, but the results were so good that it's hard to believe. The only detail that one could nitpick is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image like we have never seen in factory mode. Colour palette tests, Color Checker – everything indicated values below Delta 2. This is a much lower result than the threshold of human eye perception, which means, to put it simply, that the viewer has no chance of noticing serious deviations. It looks as if Panasonic actually calibrated this model at the factory stage. Of course, we cannot exclude the possibility that we got an exceptionally well-set specimen, but the result still makes a stunning impression. We are very strict when it comes to assessing factory calibration, and here our jaws simply dropped.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover later in the review.

The colour reproduction after calibration on the Z95B is a topic that’s hard to elaborate on, as there wasn’t much to do 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. It must be said that we haven’t had such a small range of adjustments in a long time. If any of you are particularly perceptive, you might notice minimal deviations in the EOTF curve, but this is more related to the functioning of the dynamic tone mapping feature we mentioned earlier. In reality, this isn’t a flaw, but a characteristic of this solution, which intentionally alters the brightness profile depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great right out of the box, and after calibration, it reaches a level where we really struggle to find anything to improve.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially for the manufacturer’s entry-level OLED model.

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

The situation looks worse when it comes to digital processing. Features like "gradation smoothing" or "block noise reduction" essentially do not work – the tested material looked identical regardless of the settings. We might as well say that this feature simply doesn't exist. It's a bit disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence improving image quality. Meanwhile, in such a basic matter, the television does not deliver a real effect and it looks weaker than one would expect from top-tier equipment.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

The OLED panel with very high refresh rates already provides an incredibly sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It's also very important that the television is equipped with the proprietary motion smoothing system 'Intelligent Frame Creation'. Among the available sliders, the most crucial one turns out to be the one called 'film smoothness', as it allows for adjusting the motion to personal preferences with 24-frame content, meaning films – from a more 'choppy' appearance to a smooth, almost theatrical effect. It's a bit disappointing that Panasonic didn't opt to push the latest OLED panel 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, it mainly benefits PC gamers, so in everyday viewing, it's not a significant drawback as we are limited to 120Hz.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get smoother motion without giving the picture an exaggerated soap-opera effect.

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

Although the brand is mainly associated with home cinema and equipment for filmmakers, there’s also space for gamer conveniences here. Onboard is the Game Bar (or rather Game Circles) – it looks a bit unusual visually, but it does its job and allows you to quickly check the most important image parameters. The only thing missing for complete satisfaction is actually having four HDMI 2.1 ports instead of two. It’s a minor detail, but with a TV of this class, one could expect a full set.

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.
