I've noticed every aspect of what you've mentioned, and had a GS2 back in the day - however I think that it's a manufacturing choice and not necessarily the nature of AMOLED screens. To be honest I can't wait to see how an Apple AMOLED display would turn out. I've yet to see the iWatch, but I do not think it would look like the samsung AMOLED screens i.e. overly high contrast and saturation.
ah, great point - i haven't seen an apple watch yet but that would be where to start checking out what apple does with it (duh!). i also haven't seen the new macbook - maybe a trip to the apple store is in order next week....
