Preventing OLED Degradation

Should we be worried about the lifetime of the OLED panels? A few members of my team have been leaving their Vives on and set to either the SteamVR whitespace or their desktops, and I'm worried about burn-in and screen degradation...



Lately, I've been making sure every developer's desktops are set to solid black backgrounds (while hiding the taskbar on secondary monitors) so the OLED screen is effectively "off", even when the devkit has been left on. Is this a viable technique for preserving the quality of the screen? Should the SteamVR compositor "whitespace" fade to black after a period of disuse to preserve the screen?
