Where can you (legally) get all 4k films to stream or download?

I now have a 4k television and wonder what sites are there for streaming or downloading 4k films. So on Netflix there are probably a few if you have the most expensive 4k subscription. But I don't want a few, I want ALL films that are currently available from one provider, which ones offer that? Think the Amazon Prime are not 4k right? From now on I definitely only want to see 4k content. BluRay is out of the question, only streaming or downloading.

There's no service that can offer all films.

Movies in 4k are available on Google Play Movies and Amazon Video. But not all films are in 4k, not there and generally not.

And by the way, they're expensive… Do you really have that much money?

There's neither a legal nor an illegal source where you can get all movies in 4K.

You don't even get them all on FHD anywhere.

Just looked, you can filter by 4K on Amazon Video. They cost between 4 and 20 euro ^^ hmm depends, 20 euro is a lot, but 4-6 is ok

Yes with ALL I mean all films that are already available in 4k from a production point of view, otherwise it doesn't make any sense.

I already understood that. Still not there.
