Some people who had issues after a firmware update were able to resolve, by totally powering down the tv, waiting a couple minutes, and powering it back up. Like a computer, sometimes it needs a good reboot.
Also, if you have your ATV4K and possibly other devices going through an AVR before getting to the tv, you might need to check it too to make sure it is sending the signal properly to the tv. A power cycle there can’t hurt either.
