Yes, the difference is in the pure white pouch on leucochilum as opposed to ones with spotted pouch.
Yours have pure white pouch, so I was wondering.
I have not compared their genome sequence, but I also think Paph. godefroyae var. leucochilum is probably good.
I have one named leucochilum, but have not yet seen flowers. It is supposed to be a dark variety.
I really don't care much about the color, but I really hope mine will be nice and round like yours!
