tl;dr In order to get the content in the first place, we had to sign contract that said we wouldn't distribute it to a PC, and that we wouldn't tell anyone the real reason.

Why Netflix or Amazon would tolerate that is another question. I'm not convinced they need to.

But, I'm not the right one to ask anyway because I can't get that kind of internet access from my cable company, and therefore not going to watch any 4k anything for a few years, I'd bet.
