Ok guys you're really really messing things around here.
1. You can't compare iPhone or iPad displays with your MacBook display. Neither of them (iPhone & iPad) is calibrated for reliable colors, but just for fancy colors and nice contrast. (Which sells better than a dull view that reliable colors offer.)
2. Each computer-display combination results in different colors. In terms of colors, I don't think your new display is better than the older one now. You can calibrate both with a colorimeter (Spyder4) to show the real colors. But don't compare them to handhelds which can't be calibrated!
3. Calibrating has nothing to do with getting the colors you "like", but the correct colors per standard as they will also come out correctly on print-outs when working with color profiles.
