Even 4K is not yet easily available . I mean except from AppleTV plus that all content is 4K and it’s part of basic subscription, every other streaming charges much more for 4K content, most people don’t want to pay more every month for 4K
So 8K is just a distant reality that content makers are not really wanting to happen
Wait HDMI 2.1 does not support uncompressed 8K? How much data rate you need for 8K?
