Very little, I would suggest. The bandwidth currently allocated for
broadcasting 1920x1080 is already not quite adequate to do it justice

everybody will want or could afford. So not much chance of it
happening for a long time.
Not that I am a sceptic, but the fact that you have a very logical
argument to explain why it won't happen probably means that the powers

that currently use that bandwidth.
It sounds a little like DAB, it could be so much better if it had been
