We might want to consider doing something with Airplay. I know there are a number of partial Airplay server implementation out there, so I'm not quite sure what is possible. Hijacking Airplay might be a viable option for getting compressed graphics.

On the macOS side
Airplay -> Airplay Virtual Server -> USB (compressed)

On the iOS side
USB (compressed) -> Display

Given the Airplay server implementations (or lack thereof) out there, I propose a different solution for capturing the display.

ffmpeg -f avfoundation -i "1:none" -s "1024x786" -f mpegts udp://127.0.0.1:4000
