I watched the Sunday stream, and the issue that Larry Weber brought up, as outer galaxian has noted, was in regards to the accelerated aging of blue OLED cells.
Because they age faster than the other colours, Samsung has attempted to compensate by making the blue cells in their TVs twice as large as the others (presumably using software to increase their brightness in compensation for degredation over time).
However, as Dr Weber noted, the WOLED approach used by LG avoids the problem altogether by stacking the OLEDs, so brightness should decrease evenly (if LG is correct, between 50,000 and 100,000 hours until half brightness).
Personally, the Samsung idea seems a bit of a fudged approach to solving a problem they and other manufacturers can't avoid due to LG's use of Kodak's patented method.
