Great plants! Those Calanthe hybrids are very interesting little guys!
I find that
Paph. amabile should be regarded a seperate species from
Paph. bullenianum, due to the leaf shape, texture, and differing flowers. Unfortunately, I cannot provide pictures of both species' leaves for contrast.
The plant you have does have the typical shape and coloration for
Paph. callosum, which is a completely different species, and does not resemble either
Paph. amabile or
Paph. bullenianum...
