The so-called DOF-effect in the example reminds me more of a masked subject with blurred surrounding, than a real depth-of-field. I hope the final results will be a bit better.
If I understand things correctly Samsung has done this in the Galaxy S5 already with the adaptive display mode. Take a look at http://www.displaymate.com/Galaxy_S5_ShootOut_1.htm.
Two major features I currently miss:- 100% zoom. I have to use the app "Quickpic" for that- The photo app has no view to show just those photos that are taken with my smart phone. If I want to clean up my library of all the pics I don't want to keep I have to go to a PC to do that.
Regarding the reds: Take a look at the photo on the right image border. Here the reds are more natural in the nikon picture, and too much in the canon's. I think the significance of such a shot for the results in real world photos is not so high.
