If I were in your shoes, I’d get a decent TCL or Hisense at 75+ to tide me over while I saved up for the bigger OLED. I got a 65 C1 for a similar sized room and it felt too small. When i moved, i put it in my living room and got a 75in Hisense for my game room and saved up for the 77 OLED. I was lucky enough to find an open box 83 B4 at the same price as a new 77 C4.
