For comfortable work with gui applications, 60 fps and low response time (sub 16ms) are the minimum agreeable specs. For 4K uncompressed stream, that is 3.8GiB

For comfortable work with gui applications, 60 fps and low response time (sub 16ms) are the minimum agreeable specs. For 4K uncompressed stream, that is 3.8GiB per second and the datacenter must not be behind too many routers. The bitrate would be substantially less with lossy compression (video streaming works), however text and gui elements look bad with that, so only lossless compression is reasonable. Still, I think very few places have a strong enough network connection to a datacenter to use remote server in this way. The idea isn't bad, especially with GPU prices skyrocketing last few years, but the network quality will have to go up order of magnitude to make it realistic.
