Unfortunately the Dreame Q100 is too simple, and above all too dim, a television to talk about a true HDR effect. The peak brightness we measured reaches at most about 300 nits, which is clearly too little for bright elements of the image to actually 'pop' with light. In fact, this is a level we more often associate with SDR material than with HDR. It therefore lacks the brightness headroom offered by more expensive televisions that makes highlights, reflections and the sun look noticeably more striking.
HDR colours
Fortunately the Q100 makes up for this a little elsewhere. The manufacturer markets it as a QLED television, although in practice a PFS filter is responsible for widening the colour palette. The DCI-P3 colour space we measured is covered at roughly 92%, and BT.2020 at about 67%. These are not top-tier figures, but still clearly better than simple LCD televisions without an additional gamut-expanding layer. As a result, HDR material can at least offer more saturated and varied colours, even if the brightness itself does not yet allow us to speak of a fully fledged HDR effect.
The Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode, Professional, we measured around 2,000 nits of peak brightness, so the panel’s capabilities are truly significant. Of course, with Mini-LEDs a test pattern result is only part of the story, because a lot still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform very well. Depending on the scene, the brightness we measured in films ranged from roughly 1,100 to as much as 1,700 nits. That’s already a level at which HDR has proper punch and bright highlights can be genuinely impressive. It isn’t perfect in every situation, though. With small bright elements on a very dark background the Bravia 7 II clearly favours maintaining good blacks, which can cause their brightness to drop to around 500 nits. It still looks good, but you can see the TV does not always manage this without compromise.
Colours
The second thing that has a huge impact on HDR is, of course, colour. And this is precisely where True RGB technology was meant to bring one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured about 98% DCI-P3 coverage and 88% BT.2020, so the potential to show strongly saturated colours is really large. In RGB TVs, however, the situation is a bit more complex. When we repeated the same measurements with a film background applied, palette coverage fell to around 92% DCI-P3 and 78% BT.2020. Those are still good figures, especially for an RGB Mini-LED TV, but they clearly show that the final result largely depends on how the algorithms control the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain high saturation. The biggest differences are visible in shades of blue, where samples begin to deviate more noticeably from reference values and coverage is weaker than for the other primary colours. True RGB therefore offers genuinely greater potential here, but, as with brightness, much depends on what is happening on screen.
