ID of Apistogramma sold as Viejita

[Azurrazor]

Hi!
I got a beautiful new Apisto yesterday sold as Viejita in my LFS. I've read about the Macmasteri vs Viejita ID issue, and I'm starting to suspect that this is in fact a Macmasteri (at least a hybrid?).
I think it is a juvenile male. Is it possible to say considering its coloration and fin shapes? In the store it was in a tank with a bigger, dominant male and the guy working there said that one was full size, so I'm guessing mine is not fully grown yet? Would that mean potentinally even more color in the future?

Any experienced thoughts would be highly appreciatied!

Regards

It's A. macmasteri and seems to be adult, so color doesn't necessarily enhance further.

Thanks! Is it possible that the colors are somewhat subdued because of the dominant male in the store? Would it show its true colors within 24h of being in my tank with no competing males? I guess that is difficult to answer to.

Since he is just introduced into your tank, colors will likely enhance a bit given that you provide the right conditions (e.g. water parameters, ligthing, food).
