Depends on the quality. YouTube 4k is about 25mbit/s, so that’s 3-4 4k YouTube videos playing at the same time on a 100Mb/s connection.
4k Blu-Rays OTOH can be about 50GB or larger even. You wouldn’t ordinarily stream that but you could stream one or two blu-rays with a 100Mb/s connection.
No way, that would be 6.25 MB/s for tv. For a two hour movie that would be 50GB. Is a 4k movie really 50GB?

100Mbit/s is plenty for current use-cases.
