You can look at the results at different saturation levels for the iPhone 5 and see that all the intermediate saturations are almost spot on. It's not too saturated (which the Galaxy 3 appears to be), but accurately saturated where what you see on the screen accurately reflects what is in the source content.
Though, I'm not sure if it's such a good thing (might be a little too saturated for all I know, but probably isn't).
