The Dreame Q100 is unfortunately too simple, and above all too dim, to really deliver a true HDR effect. Our measured peak brightness reaches at most around 300 nits, which is definitely too low for bright parts of the image to really "hit" you 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 TVs, which makes highlights, reflections and the sun look noticeably more impressive.
HDR colours
Fortunately the Q100 makes up for some of that elsewhere. The manufacturer markets it as a QLED TV, although in practice a PFS filter is responsible for widening the colour palette. Our measurements show coverage of about 92% of DCI-P3 and around 67% of BT.2020. These are not top-tier numbers, but still clearly better than basic LCD TVs without an extra layer to expand the gamut. That means HDR material can at least offer more saturated and varied colours, even if the brightness alone does not yet allow you to speak of a fully convincing HDR effect.
Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode for watching, Professional, we measured about 2,000 nits of peak brightness, so the panel’s capabilities are truly large. Of course, in Mini-LED sets a test-pattern result is only part of the story, because much still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform really well. Depending on the scene, the brightness we measured in films ranged from about 1,100 to as much as 1,700 nits. That’s a level at which HDR has proper punch and bright highlights can be genuinely impressive. It’s not perfect in every situation. With small bright elements on a very dark background, the Bravia 7 II clearly prioritises maintaining good black levels, so their brightness can fall to around 500 nits. It still looks good, but it’s clear the TV doesn’t always manage this without compromise.
Colours
The second thing that has a huge impact on HDR is, of course, colour. And this is where True RGB was meant to deliver one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured roughly 98% DCI-P3 coverage and 88% BT.2020, so the potential for showing highly saturated colours is substantial. In RGB TVs the matter is a bit more complex. When we repeated the same measurements with a film-like background applied, gamut coverage dropped to about 92% DCI-P3 and 78% BT.2020. Those are still good numbers, especially for an RGB Mini-LED TV, but they show that the final result largely depends on how the algorithms drive the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain strong saturation. The biggest differences are visible in blue shades, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primaries. True RGB therefore offers genuinely greater potential, but, as with brightness, a lot depends on what’s actually happening on screen.
