One can never know for sure as they share a common ancestor (Skip Bartlett), but given the choice between the two, I would say that it is Lunacy (Hellas x Skip Bartlett). In-Charm White (White Knight x godefroyae) would tend to have wider petals. Here is a first bloom Paph Lunacy currently in bloom.
looks very similar to one Paph. Lunacy that i got in a compot years ago. every one was slightly different, some were short stems and a couple had taller stems like yours. flowers had different colors in the pouches as well
