I’ve read that 8k streams can exceed 100mbps. I have not dig very far into that though since I don’t have an 8k tv or any 8k sources.

Streaming services are extremely compressed. Netflix only recommendeds 15mbps for 4k, even. A naive straight quadrupling of that for 8k is only 60mbps, and in reality they'll just dial up the compression anyway and probably use a 30mbps stream.
