Netflix only streams 720p unless you use Edge on some edition of Win10

Unless you're sitting closer than two screen diagonals to your TV, it's a scientific fact that even with 20/20 vision you can't tell the difference between SD and HD.

Please reference the NHK's book on their analogue HD technology, Hi-Vision Technology, where they go into the psychovisual research extensively.

I used to think that too but when watching GoPro footage over the years there is always a visible difference between 720p and 1080p. And I think 4k is also noticeable.

I agree they are all noticeable, at the proper viewing distance. These are scientific facts. Ask yourself, what's the smallest angle the human eye can subtend? All other factors fall into place once you've calculated this.

I didn't want to go into details, but I think we actually get Netflix in 1080(p?) using either Firefox or Chrome, but Amazon Prime looks like 720p using Firefox.

If you know how let me know. There used to be an addon that mimic'd a header it was looking for but I think netflix fixed that loophole. Im not sure if there is a way to verify the info during playback anymore?

EDIT - From their website (https://help.netflix.com/en/node/23931):

    Google Chrome up to 720p
