The Galaxy S4 has a good screen but it's a little too over-saturated giving unnatural skin tones. Switching to "Movie" mode results in rather muted colors. For accurate color reproduction there's a new app "Calibrated photo Viewer" on Google Play with pre-calibrated color and gamma corrections to show photos in their natural colors.

Adobe RGB and sRGB color spaces are supported so both standard and professional photos can be viewed seamlessly, without the need to switch 'screen modes'.

The app works just like a normal photo viewer. No rooting is required.
