Phalaenopsis leaves changing pattern

[Dutzy]

Hello everyone, so I have a bit of a weird question. Has anyone had a phal that changed leaf patterns? The reason I'm asking is because I have this odd little hybrid here, that may be a schilleriana or stuartiana cross, not sure which one, but it is starting to resemble some one of species because of the leaf pattern. The funny thing is that when I bought her she has almost completely green leafs only a few spots that I thought, back then, they were some kind of damage, and now she is putting a new leaf with an even bolder pattern and red underside. I'm just curious if anyone has seen or had something similar before or has any thoughts, impressions, opinions. Thank you
