It seems to me that if you are going to a fancy soundbar, you have already compromised your sourround sound, so I would just make sure that the 85” TV is the best OLED out there. For me, the larger size and great black levels make the movie experience much better than lacking either size, or great black levels.
TV size for Sonos arc
Is 85" too large for Sonos arc imaging? In pursuit of decluttering I'd like to replace my surround setup (Bryston SP3, 2 NAD stereo amps, and 4 LS50s) with a Sonos arc, leaving only a single rack of Ayre gear and KEF Reference 1s for stereo. An Ayre stereo amp and 2 JC 1 monoblocks sit on the floor about 2' from the wall on which the Sony TV is mounted. Would they interfere with Sonos imaging? I hope to sell the JC 1s as part of decluttering.
