I use my OLED mainly for PC gaming. Little of light browsing. Usually when I do that I use a full screen browser. My taskbar is set to auto-hide and my wallpaper is set to all solid black. No icons. When I have everything minimized it looks like the display is turned off. Because essentially that's what it is. All pixels are off.
OLED is profoundly good. Since going to OLED I don't think I could go back to anything LCD. Even if I ever do experience burn in, I'll just move that display to another room and get another OLED. They aren't really all that expensive anymore.
