There is a browser extension called “Netflix 1080p”, but in my experience the quality isn’t the same as Netflix’s native 1080p - the quality with the extension is visibly lower (but still better than 720p). And of course, it can’t do 4K at all. It also occasionally breaks, which is annoying.
If you really want to play streaming services at full quality, it’s better to just get a streaming stick like a Fire TV Stick, or a Roku or similar.
