Yeah, I'd recommend you stick to things with simple mechanical buttons or something.
When you press the power button and it goes to art mode (effectively a screensaver) instead of turning off, most people's next step would be to try holding the power button. Barring that, the manual clearly describes these two different operations if the power button.
As an experienced developer who has done way too much networking and home automation for my own good, it never would occur to me to hold the power button on a remote.
And now I just discovered my Apple TV actually has a control panel. You don't need to go two layers deep in Settings to put it to sleep. It never occurred to me to a long press on the home button would do anything. (Despite knowing long pressing on the menu taking you to the main menu.)
