The icon isn't the photos app icon, although the general shape is similar.

>Add details cautiously. If the content or shape is overly complex, details can be hard to discern. Icons at all three sizes should generally match in appearance, although you can explore subtle, richer, or more detailed additions at 48×48 pixel size.

I believe that example is meant to be an example of a bad icon, as it has a complex shape with lots of different textures.

are you sure? I'm holding up my iPhone side-by-side, an to me there's no doubt this is attempting to represent that. To represent the different colors, the pixel version uses a unique pattern for each "feather". It seems as 1:1 as a 48x48 pixel version could be.
