Although not a macro-related problem perse, these look great at the size they are taken, zooming in or enlarging them a little bit shows some of the flaws (overly processed, computational errors).

These pictures have been made by people who have photography as a serious hobby and know what they are doing, hence the well-lit and positioned scenes. I have not been able to make a picture like these without a lot of effort. But it is possible.

That said, it's a pretty incredible feature so far!
