Indeed. It's probably the most revealing part that this is not real including the snapdragon part. Samsung have not yet given S AMOLED to any other manufacturer and looking at Galaxy S and Wave selling like hot cakes i don't think Samsung is in hurry to give it and might not even have the capacity for it.
Plus Nokia very rarely gets it's hw parts from Samsung.

As a Galaxy S owner i can also say while the screen is nothing else than amazing on videos it got the same problem that Nexus ones AMOLED got where the actual resolution is not 860x480 and that really shows when you are looking at lots of text especially on this 4" screen.
