Good quality comes at the expense of latency through the jitter buffers that reconstruct the audio after the packets have been lost or delayed. You can't have both quality and low latency. There is no sweet spot in the middle where they are both good.
Yeah, on a LAN it works because it's probably a "modern" switched ethernet or a simple one (everything on the same bus) but with only a couple of computers and very low traffic, so very little frame collisions. In that case, UDP will work very well for the same reasons you can go 250Km/h in an empty motorway in lockdown times: it's a straight line and empty, there's nothing to crash into.
The moment you introduce traffic and routing you can't get even remotely near these speeds.
The old modem PPP protocol between two modems over a switched telephone line (not tunneling into an IP network) might work better - at least to jam in two.. too bad nobody uses modems anymore and the quality would be probably still pretty bad.
