I'm using an LG OLED TV (2018 model I think) with an Apple TV, and it's working pretty much exactly like a dumb screen. I haven't connected the TV to the network, and I control everything with the Apple TV remote - it turns on the TV via HDMI CEC as needed, and when I turn off the Apple TV the TV turns off too. I've also connected my home theater system via HDMI ARC to get better sound, and CEC turns on and off the speakers too. All I see of the LG interface during normal use is a small box in the top right corner that says "Apple TV" on boot and "Denon available" or something like that when the speaker systems has booted. Also, the screen turns on quickly so there's practically no waiting for anything. I was thinking of getting one of those in-store displays instead of a TV, but they don't usually have HDR. A++++, would buy again!
