I have one that looks just about like that one, but the colors are a bit brighter. That may be the camera or lighting though... Mine is a standard every day no-namer favia... There are many that come in without names so I would just consider it a cool find and see what it does when it grows out.
Unless you know the lineage of named corals, the name is just too hard to prove to someone if they ask. Since you are asking, I assume no lineage exists, thus no-namer or lookalike is all that is claimable
