Why are Pokemon in my Photodex marked with a crown?

Some of the Pokemon in my Photodex are marked with a small sparkling crown icon. What does this crown icon mean?

Photodex with crowns


Solution 1:

A Pokemon is marked with a crown after getting a photo for each of the 4 star ratings. The crown is visible on both the individual Pokemon page and on the list of Pokemon.

Note: The "updated" icon (!) will take priority over the crown on the Pokemon list.
