OLED only burns in if the content is static for hours. If your head is that stable while using VR, I give you $5.
* cooled aggressively
* constantly changing colors (more even wear)
But it is still always losing durability in a steady way.And even if fully static contents were a problem, I guess the foveated streaming would introduce enough noise to counter burn-in.
Static objects in your view are VERY nauseating (at least in my experience).
