Yeah, I like to watch anime, and most of it (if not all, I'm not sure) is only available on 1080p and it doesn't look nearly as bad as Netflix want us to think lol.
I also watch Netflix with my Nvidia Shield TV which has a pretty neat AI upscaler, but honestly any good upscaler nowadays would do, I mean lots of content is available in 1080p and that doesn't looks like changing for the foreseeable future.
I've got a 1080p TV. I have had it for 10+ years and I will continue to have it until it craps out.
I've seen 4k. Yes it's better. Is it better enough? Not for me, and my eyes aren't getting any younger.
I also save money, since gaming at 1080 with great framerates is much easier too. And storing 1080 media etc (hell, even 720 with upscaling isn't too bad).
I guess my point is: come at me Netflix; keep annoying me with your ads. They literally have 0% chance of success.
