So I feel better about this TV after yesterday. In the afternoon, it got really sunny in the room because of the skylight, and I didn’t need to pull curtains or anything. The image was nice and bright, no reflections, no blooming. Later I played Spider-Man MM on PS5 and the colours and HDR were punching my retinas hard.. so good! Then at night I was watching DV content and got turn off by the blooming in black bars again... until I switched from DV bright to DV dark. It really made a difference! Subtitles blooming was much more subtle, noticing them only by looking at them really closely. There was still occasional blooming in black bars with bright objects, but really, it’s not that noticeable when you’re actually watching the show instead of looking at black bars all the time. Next thing to do is to find similar settings than DV dark to watch SDR and HDR10 contant at night.
So in conclusion, the pros really outweighs the cons here when speaking about brightness.
I think I’ll keep it. As much as the J series is tempting, we don’t know anything about their blooming performance yet and I’m not waiting a year to have a decent price. Life is short.
