Apple likes their pictures with a little bit of warmth filter and a boost in the shadows. Kinda like a mild instagram for all their pictures out of their camera. Not really accurate so it'll always underperform according to accuracy. You talk to people out in the wild, they'll always say "I don't know what it is but iPhone always takes so much better pictures" because they judge based on emotion, not technical accuracy. The Galaxy S6 and Note5 ( S6 with RAW/DNG output) is more of a best available camera on a smartphone to bridge the gap between cameras and smartphones, while Apple is just trying to produce a better jpeg files for mobile use. Different schools of thought. There are advantages to both.
