Disable Wi-Fi, Reduced Latency?

We've always been able to disable Wi-Fi (thank you bsteiner), but since v9.2 we can now disable it via the app. I hope this means Sonos is now officially supporting wired setups. Sonos generally has a buffer of c 83ms yet Playbar-surround Play 3 same-room pairings ("Surround") , are at only c 30ms. The buffer is obviously to deal with packet loss/sequencing, and multi-room WiFi audio is likely to suffer more from that than would same-room peer-to-peer Surround connections. I would think that mutliroom wired audio would suffer even less packet problems, and could live with an even smaller buffer. Obviously this would only be the case if allunits were hard wired. Does anyone know whether Sonos has implemented code which can detect a fully-wired system and reduce all buffer sizes accordingly? This might seem like an arcane point but the advantage of such functionality would be that users could use Sonos speakers as TV Front Center and Left Center speakers without horrible lipsync problems. I would like to do that so that I can use by Play 3's for TV and for audio, rather than needing two separate sets of speakers. Yes, I know, I could use a Playbar/Playbase but we have a TV on a movable stand in the center of the room and P/P just don't work for us.
