Can someone tell me what type of koi this is?

[SaphireLongfin]

i've been told several different things. i just want to know what type of koi she is, all we know for sure is that she's a butterfly koi, what type we have no idea, can anyone help. someone told me she was a german scale? but i havnt been able to find any reference pictures, another person told me shes a Kajuku Doitsu or something like that and when i looked them up the scales werent as big as hers, i'm fairly new to koi, so i dont know much about it, i'd love to know exactly what she is if possible. i know her scales a re huge compared to the other two we used to have
