Beautiful!
It does look the same, but you still cannot say what it is for sure because other hybrids involving lowii and a paph in the sequential flowering group will produce about the same looking flowers.
I think the closest you can go is lowii (which is obvious) and a member from cochlopetalum.
Even the one you found on eaby is a representative picture of that hybrid. While primary hybrids are much more uniform than more complex hybrids, they do show variations, especially in the shape, making it awfully difficult to tell.
The same goes with hybrids made with multifloral and sequential. It is just nearly impossible to tell because hybrids of this type is just so so similar in phenotype.
