Going back to your original post, I think what tends to happen with mobiles is that, even though you don't see it, they basically do an HDR process. they may only give you one photo, but they'll take an number of photos and stitch them together to try and achieve the 'correct' exposure in every shot.
So that original shot looks too heavily saturated and has that slight over-done HDR 'false' look to my eyes. It can be a good effect, but not if that's all you ever get.
I also had a similar issue with a lot of early PAS digital cameras in that they always seemed to try and get everything in focus. Which also looks false.
