>You'll see webrips all the time with 1080p because someone can just record their screen and call it a day.
I've checked my tracker and practically all TV shows from Netflix that are in 4K can be downloaded in 4K. And I am 99% sure they are not screen caps, for example the entire second season of The Witcher was released 17 December at 09:01, and my tracker had it ready to download at 12:26 at 4K with 3 audio tracks and 2 subtitle tracks. The runtime of this season on imdb is about 8 hours, so it would be impossible to screencap, which means they had a bypass for the DRM ready ahead of time.
Of course these are just examples that I made up and I would never enter or use such filthy and illegal websites.
And for the mobile and smart TV experience there is Plex. It even has features which aren't possible with the legitimate services, such as "Watch Together" which allows you to watch stuff with friends over the internet.
