It's no worse than on a phone. I've never noticed burn in on any OLED phone or my current laptop (although the latter is newer). I'm using a thinkpad X1 yoga OLED. The biggest danger with this device is using Windows, as the drivers for the display panel have a bug in them that will lead to degradation and destruction of the panel. Using Linux avoids this issue.
