Owned this set for a few weeks now, and it replaces a 50" Panasonic GT something or other plasma from about five years ago. My other television is a JVC HD750 projector.
A few potential problems have been mentioned in various reviews.
(1) Dirty screen effect and/or banding
Different things, but neither noticeable on my set. Possibly I've been lucky.
(2) Viewing angle.
Staying within 30 degrees, preferably 20 degrees of the screen perpendicular is a good idea, particularly as there is a tendency to sit closer to a UHD screen.
(3) Motion handling. A low level of frame interpolation clears things up with a minimum of artefacts.
Better than my projector. No plasma style paint-by-numbers collapse of bit depth.
(4) Haloing. I've yet to watch the Martian on it, but I've yet to notice anything objectionable.
This is the first time I've viewed HDR material. The greater dynamic range in association with very bright peak whites can look fantastic. It can also be unpleasant and blinding. I'm distracted by the searing brightness before I become annoyed by halos!
The television does what it does to specification, and it's down to the film maker to provide an enjoyable image.
