I think there's a lot of confusion here. For instance, saying that N8 had "true black" is a joke. The Nokia 808 did, yes, and it's amoled, with CBD.
Now you may wish to read this great article by Steve Litchfield; there are : ClearBlack (1020, 808), CB Lite (640, 630) and no clear black on the market.
(skip the Pureview part and go the ClearBlack section) :
When a brand name outlives its founding technology: PureView and CBD
I think the 950, being high end, will have ClearBlack (the real stuff) with non LCD/IPS screen.
