Your admonition to go with Oled over QLed seems reasonable though for my living space I have questions about whether Oled will have a bright enough image for the space it must go into.
OLED has come a long way in this regard. This was the main concern we had since the television would be situated in our living room next to a long sliding glass door that leads to our backyard. During the day it’s bright - you can check my virtual system for reference and comparison. In the past month we went with an LG G4 and it’s plenty bright; almost blinding at times. The model below, the LG C4, would have likely been okay for our living room.
I was in Sam’s club the other day looking at their offerings, and was looking at 85" models for our living room and noticed that if was sitting a bit offset from the center of the screen as I normally would be, the part of the screen furthest away from me was washed out compared to the direct on view on some models. I had read about some screens having these kinds of issues but didnt realize how pronounced a problem that could be. It seems Oleds solve that problem and have great wide angle viewing. S
Beyond the blackest of blacks that OLEDs produce, the viewing angles are another strength. For example, in my living room I can sit on the side couch and not feel nearly as compromised as my previous IPS panel/television.
