Panasonic W95B vs LG OLED B6

The Panasonic W95B is truly a bright screen, capable of achieving peak luminance levels of around 1400 nits. In brighter, well-lit movie scenes, this value translates into spectacular HDR effects that can leave a big impression. However, knowing our test setup, you probably see that in very demanding shots – such as the moon in the distance or the lights of a helicopter in a scene from Sicario 2 – the television doesn’t impress. In such situations, brightness drops to around 200 nits, making the HDR effect much less noticeable. This happens because Panasonic focuses on maintaining deep blacks, not illuminating the background – which shouldn’t be a concern for many users. However, it’s important to remember that in such moments, the picture starts to resemble SDR content. The coverage of the colour palette also deserves praise, as it reaches around 93% of the DCI-P3 space thanks to the use of the PFS filter (also known from QLED technology). This means that most films look very good in terms of saturation and colours, maintaining a cinematic quality to the image.

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.

In Filmmaker mode, the Panasonic W95B offers an image with quite accurate colour reproduction, although it is not without minor imperfections. The white balance slightly leans towards red, which can cause a subtle warm tint to the image, and the gamma curve is slightly elevated, making the screen appear a bit brighter. It's good that the manufacturer has included this mode – even in its factory configuration, it provides a fairly natural look for films. However, knowing how susceptible Panasonic televisions are to calibration, we decided to check how much the image could be improved after professional tuning.

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.

After professional calibration, the Panasonic W95B shows what it’s really capable of. Colour errors have mostly dropped below values of 2–3, making them practically invisible to the human eye. The excess red in the white balance has also been corrected, which means the image is no longer slightly tinted pink, and details in dark areas no longer get lost due to excessive dimming in the gamma. The improvement in HDR content is also noticeable – colour saturation is now more stable and doesn’t lean towards blue as distinctly as it did before. It’s truly a fantastic television for watching movies and series in the highest possible quality. While we know that Mini LED screens are not always perfectly suited for this, the W95B is a prime example that with proper tuning, a result close to OLEDs can be achieved.

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.

In terms of image processing, the Panasonic W95B performs exceptionally well. The proprietary processor responsible for digital image processing effectively upscales lower resolution content to 4K, maintaining a high level of detail and a natural look to contours. The end result is impressive – the upscaling is truly top-notch, and Full HD content can look surprisingly good. Also noteworthy is how the TV smooths tonal transitions in low-quality materials. The algorithm doesn’t operate as aggressively as in some competing models, which helps avoid the loss of detail or the blurring of film grain.

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 144 Hz panel used in the Panasonic W95B offers excellent smoothness, although in practice, given how television content looks or how new-generation consoles are limited, it’s worth looking at its performance when refreshing at 120 Hz. In this mode, the television performs exceptionally well – despite being a VA panel, which is not known for the fastest pixel response times, motion blur is minimal and difficult to detect with the naked eye.

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.

Aside from the previously mentioned issue related to VRR mode, where local dimming does not work, the Panasonic W95B is a true gaming beast. The TV offers practically everything that gamers could expect – perhaps apart from four HDMI 2.1 ports, as there are only two available. On board, we find automatic low latency mode (ALLM), correctly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. The whole package is complemented by an interestingly designed Game Bar, presented in the form of circles. It may not be the most visually attractive, but it fulfills its purpose – allowing quick access to key game parameters and adjusting settings without diving into the system menu.

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.
