(If any of what I say below is factually wrong, please contribute. I would very much be interested in knowing why or what is causing the blue tint)
I've been trying to study up more about this, though I don't think many people still have a real understanding on the technology behind Super Amoled screens. What I mean by that is, I have yet to find a formal write up explaining the bluish tint.
From what I have read however, it could be a software issue (Screen color-calibration, in which a screen-calibration app could be developed) or the Super Amoled screen's are manufactured that way on purpose. I read from one place that Samsung did that on purpose, because the first color pixels to die out first are blue...
...if that is true or not, I have no idea. I think most people are speculating these reasons for the bluish tint. If I had to guess, it would be that Samsung uses a certain coating on their screen, in the same way you would see different lens coatings ranging from Canon, Nikon, Olympus, Panasonic etc., on there photographic lenses. Just my 2 cents...
The facts that I do enjoy most, of the Super Amoled vs Retina are as follows:
Super Amoled:
Contrast ratio - 100.000:1 (No back light = true blacks)
Resolution of 800x480 @ 260ppi
Retina:
Contrast ratio - 800:1 (back lit)
Resolution of 960x640 @ 326 ppi
So the Retina screen does have a crisper clearer screen for reading text, but not great blacks and colors compared to the Super Amoled screen. Also, the viewing angle and outdoor visibility is supposed to be better with the Super Amoled.
Lastly, because there is no back light with the Super Amoled screens, there is far less battery consumption. With all that said, it is again, a personal decision. It will be a few more years for all the technology to come together for someone to produce the 'perfect' screen. If perfect is something even obtainable. Nevertheless, I watch more TV, movies and view photos than surf the web or read books, thus, I prefer the Super Amoled screen.
