I'm afraid everyone who has ever purchased anything online sight unseen, has had issues with the item not being what they expected. This doesn't mean that the item was misrepresented.
Sorry but it all relates to the grade, in doing research this would have been the question to ask. There are fine lines in what labels a fish as a picasso.

Please read the last line. For $60, you got what you paid for. I know that's not what you want to hear but it is the truth. You have the genetics. If you want just a show fish, you would have to purchase a higher grade.
This is an adolescent fish and will develop color a bit more as it ages. I have seen some that have really changed their look as their black develops.
