My take is that there are only two kinds of AMOLED screens coupled with various gimmicks RGB AMOLED (E7, i8910, SGSII, 900, N85 et al.) PenTile AMOLED (Nexus One, SGS, N9, RAZR et al.) "Super" stands for the gimmick that it has the touch sensor integrated "CBD" stands for a polarizer filter on top of it (Nokia only, samsung also have polarizers but don't advertise it) "Plus" stands for non-PenTile (Samsung only - Nokia also has RGB Stripe screens but they don't advertize it) 98% of AMOLED Screens are made by Samsung according to wikipedia, so probably Nokia and Samsung screens are the same. The deciding factor is probably the subpixel size. They start from what res and size they want and if it fits they go for RGB, else they go for PenTile. I expect Samsung to keep the higher res RGB screens for themselves for some months before licensing them to others, so that it helps them achieve World Domination™
