The current setting is definitely horrible and not working correctly. Screensaver should *NOT* come on when I have apps running like Spotify or Netflix. Like Dave, I don't want to have to keep pushing buttons to follow along with what songs are playing and what lyrics the songs have.
I get that it is burn in protection, but I paid good money for this TV and I prefer for it to work the way I want it to and disable any "protective" features if I don't want them, rather than be forced to stare at a black screen with a few dots pretending to be "fireworks".
