The tags say Paph Supersuk 'Eureka' AM/AOS X Raisin Pie 'Hsinying' X sib

With that said, the first flower is something I have never seen out of this cross, but it is definitely possible and one can easily see it too, it's very much barbartum with dark color.
The second one is something I have seen quite a few of, actually.
So there!

Agree with you on the fact complex Maudiae hybrids can be variable, but the second one shows strong dayanum influence, which I think is not in the lineage of either of the parent plants...

I can see why some people including you would say dayanum influence, but this shape is not oddity coming from such complex hybrid.

Any species involved in the making of this plant can contribute a little bit here and there making the whole picture.

Anything that has sukhakulii and curtii can have dorsal and sagging pouch like that. The long skinny petals come from lawrenceanum...

The color scheme is easily achievable given that it has mastersianum in it mixed with all other species in the background.

ID is your guess. I like the day anthem looking one a lot.
