A game changer would be something like 4k streaming with no compression or something along those lines.
Uncompressed video tends to use an infeasible amount of bandwidth:
width × height × bits per pixel × frames per second
(3840 × 2160 × 24 × 24) = 4,777,574,400 or approx. 4.8 Gbps
Say more along the lines of blueray quality I know some of my 1080p Bluerays use >50mbps.
So 4K streams could be less compressed and run at higher rates such as 60-120mbps, 8K seems more likely however as I'm pretty sure you need 140mbps to stream it even with h.265.
