Nope, that's a full flowerhorn alright. But I can't give you exact detail of which type of FH strain is that fish carrying. But I've seen multiple FH like that with no flowerlines at all just pure pearls all over. Still a good fish...
He looks like he has some texas in him for sure. He's very pretty. It's hard to say about the KOK, they can burst out at any time, it can take a while.
