I can finally share mine. Still don't have a rug and half the furniture but it's finally where I play games. In a month the room should be totally finished, and decorated properly. Lots of placeholders on the shelves.
Went with the Qn90a, 85inch - didnt do OLED because of the windows. The tv far exceeded what I expected to see during the day, it looks incredible.
It's a ridiculously oversized room and took a fair bit of effort to make it feel well proportioned. We took this wall down to the studs and designed the fireplace & mantel around being able to put an 85 in here - the previous owners had a sad little narrow fireplace with a 55" that went from edge to edge.
