TV info says I’m only getting 1280 x 720 / 60p Roku says I hav Full high Definition (1080p) 1080p content protection (HDCP 1.4) Roku will only display 720p
Apple TV model A1625 HDMI Firmware 17.28 will do 1920 x 1080 / 60p on same TV
Shut down both Roku and Apple TV. Unplug the HDMI cables from each, leaving the other ends connected to the TV. Plug the Roku HDMI into the Apple TV, and the Apple TV HDMI into the Roku. Do the symptoms remain?

Change (or switch) HDMI cable so you get HDCP 2.2 on the Roku box and you will get the higher framerate option (60 fps) with higher resolutions (>=1080) instead of being stuck with 720p at 60 fps. The current cable can probably only do 1080p at 30 fps'ish.
