Betta Fish: Help with ID re:colour/fin variety!

Hi r/betta!

New to reddit, long standing fish keeper here!

Last year I took my first break from the hobby in 2 decades after moving to a fantastic new unit that wasn't a fan of the liability associated with my large fishtank.

Fast forward to renewing my lease and got the go ahead for a 5 gallon Betta tank (I mean, technically it's 6 but who's doing the math) and got this stunner as the piece de resistance! Brought him home a few days ago.

He was labeled as dragonscale, and looks similar to red dragons online, but past that I've got no info.

My thoughts after going down a few hours of research rabbit hole:

He has some fin damage (already starting to heal) and all that clear butterfly ish border seems to be changing colour to red and iridescent now that he's in a filtered heated tank so I'm not sure it'll stay. I don't know that his metallic counts as the silver/white for true dragons- its turning slightly multi toned iridescent in the new conditions. He might be young enough his tail is still maturing but unclear. His fins are giving me rosetail maybe and his tail is giving me half moon/over half moon? It definitely goes past 180° and even fully extended it's giving petal vibes with extra ripples on the rays.

I'm wondering what his colour and fin type are and was hoping you guys could help me out!
