Btw, the burn in was most visible when that section of the screen was showing one color, regardless of what that color was. It was visible on a white screen, a green screen. While visible on a screen displaying content, it was visible, just not as visible as with a one color screen. I didn't think to take pics on all types of screens, as the pic I took was representive of what was visible. The picture I took was part of the loop. It just so happens that that section of screen was showing a blue sky when I took the picture. As for the Samsung, Robert advised me after reading my piece that the Samsung uses a RGB system not LG's WRGB system.
That the display is showing the same effect on any single color screen, even a green screen is further significant evidence (pretty close to proof) that the display is not showing aging of the blue emitter but rather there is something else at work there.
