But given that you have a 4K RED setup in your bedroom with a studio microphone, what technology actually preserves most of the quality over the video call? Let's say both participants have fibre connections and located in the same city.

Plain old RTMP stream with h.265 inside probably. The problem is that nobody uses this for streaming because h.265 encoding is expensive even for hardware encoders in GPU. So to satisfice, use h.264 at good bitrate. Over 80 Mbit should be fine ;)

How would that work? Which application supports it? I don't know of a native way to do this.
