Appears to be a manufacturing issue. System Info says TV is 58R6+........ it isn't. The TV is a HiSense 55R6E.
Being able to downgrade the System Software would be helpful too.
This is becoming exhausting. How do I put the TV info Manufacturer Mode, change the setting and call it a day? I can upgrade firmware if needed too. This is trivially easy with other devices I work on.
