I don't grow to many Paphiopedilum but I don't have any problems to make this plant often.
It is a beautiful blossom, i found they are not easy to grow, specially when it comes to watering. in nature they mostly grow on rocky soil that provides a very good drainage. so, a little bit too much of water means often that bacteria will attack. here on of mine which i planted in a mixture of bark 50% and dices of coconut shell 50%
The plant shown was exhibited as species, but personally I think that this one is a hybrid understanding that species ask for identical parents. The normal species known to me show the purplish spots not that "dense". What do you think?
