It's not photoshopped, it's just cropped to show you their wide angle vs a typical camera. Quoting the website, directly beside the picture you've linked:
"The extra-wide 80º viewing angle captures more area than other phones so your pictures will include more background without distortion. "
Um, the point isn't about photo quality in the comparison. I have to agree that it's confusing, but actually they're trying to highlight the fact that their phone has a wider viewing angle. (If you look, their picture includes more people.)
The two pictures are identical! They've photoshopped the original to look shittier, and passed it off as being taken by another smartphone.
