No 4k channels

Why am I paying for 4K boxes when there are no 4K channels available? All I can do is watch 4K content on streaming apps from other companies. The support info makes it seem like there are 4K channels that the system will autotune to, but this is [Edited: "Language"]. There are no 4K channels to auto tune to. I’m paying extra money to be able to access other companies streaming services through my cable company. Why am I doing this?
