I think it is!.
It's the growth form that is unique!.
The Green fluorescent protein expression occurs often when corals are in recovery phase and your green will likely disappear eventually... I think led's stimulate more GFP expression too ( personal opinion).
I have had this coral on a Mari shipment from ?Bali several years ago, but lost it when Biopellets came out and I overdosed. It went from green to tan and then the bright purple tips came out., but you need to wait for the long spindly growth to be sure. It is unique!.
