"If you know that the receiver is going to receive all of the data that you send (or at least a lot of it at once, for example if you have a 5-second buffer), then you can more efficiently compress all of the media being sent."
That has nothing to do with the underlying transport.

Here you're describing a bunch of possible properties a hypothetical protocol written on top of unreliable datagrams would/should have.
"I should say that this isn't about TCP vs UDP so much as..."
This part is correct. You should keep this part.
"..it is about buffered vs realtime streaming."
Right. Let's not conflate transport protocols with media streaming methodologies please.
