What I've heard, laevigatum is a smallish growing plant and likely smaller flowers. Paph roebelenii supposedly doesn't have green in its veins but the same color as the staminode itself. What I find most interesting is the color of your staminode! It's white! With veins the the same color as the pouch, yellowish.
I have a plant tagged laevigatum and I haven't seen it bloom since 1999! I almost kill it dead but it has come back. One mature growth with 2 starts so maybe next Spring.
What I do remember is my flowers have the same shape as yours.
