Im now proud owner of an 82Q70R.
This tv is replacing a 75Q8FN, I enjoy the larger screen, there is no replacement for displacement. Last evening I was able to sit through an NHL game and enjoy it, very little if any dse on this 82, I cant say that about the Q8 which has terrible dse.
Using an Aptv 4k box I use to stream DTVN, most things look sharper and more clear than they ever have. Colors look good and not to much overblown. Brightness is good as well. Watching Avengers infinity War looked better than ever, bright highlights popped and were not overcooked, great contrast, the dimming works a bit better than the Q8. Also watching lower quality content the noise reduction capabilities are an improvement.
Also there is 2 different positions you can mount the stands, inwards or farther out. I will measure those later.
