Turning dim and black as soon as possible is actually the best for an OLED. A traditional screensaver is a net negative. The built-in fancy-mitigation systems are also probably better than any intermittent fancy screensaver (without the ability to analyze the panel wear to be corrected directly), but at least that's angling towards something better than a loss.
Of course, screensavers are still plain fun. That's justification enough to set one if you want.
