You clearly dont have a modern OLED or streamer. At least on Apple TV set top, if you pause anything for more than 2mins, the screen saver comes on. If the screen saver plays for for 10mins, it turns the TV off via HDMI. If the Apple TV just turns itself off, the TV itself has a screen saver and will do the same for itself. My LG also has built in pixel refresh mode that does its thing every 6months months on its own when the tv is noff, how, I dont know but it tells me its gonna do it. I watch alot of news channels, so there are logos that stay on the screen for along time, no burn-in.
