ICloud video streaming

I'm having a problem finding any solid info as to why I can't find any info on this subject. Right now I have my library of movies and tv shows in Google One and stream that content to my various devices through infuse. Why can I not do the same with iCloud? I don't care if it's with infuse I'll use whatever, but everytime I try with file apps and such it always downloads a copy to my device and then plays it rather than streaming it directly like with Google. With one tb of content ii no the cloud I can't have that downloading onto my devices so they can play, I need them to stream from the cloud. Right now I use mostly apple services and would rather not pay for iCloud drive space and Google one space, rather would like everything in the apple universe.
