TVs once had a simple input button on the controller. Now there’s just the Home Screen that you described. It’s very confusing to use
The part that is really interesting to me is that they seem to be desperately trying to get me comfortable with some kind of "It's not TV, it's Samsung TV" attitude, when what they're actually accomplishing is convincing me that TV just sucks now and it makes me loathe Samsung. It's as if they hired a guy to sit next to me on the couch and every once in a while, he pokes me with a sharp stick and yells "SAMSUNG!"

there is not a button to change inputs. You have to go to a home screen and the inputs are commingled with other options like streaming apps.

and of course they 'intelligently' hide inactive inputs
