I actually just found it on LG's website. They have what LG is called and Anti-retention Cycle.

From the Article :

"OLED Image Retention or Burn-In: Burn-in and image retention are possible on virtually any display. However, with an LG OLED TV, any risk of burn-in or image retention have been addressed through the use of technology that not only helps protect against damage to the screen, but features self-healing properties so that any short-term image retention that may occur is quickly rectified."

Again, is this BS on LG's part, or are they really self healing??
