Interesting whitish violacea

This is an interesting plant among a batch of Phalaenopsis violacea var coerulea (x sib) from WL.  The flower is almost white but has a pinkish tone (rose white) and the lip is lightly pinkish.  Really beautiful flower.  Since whites can come from bluish sibling cross i wonder how many of the violacea alba out there are truly descendants of wild collected violacea albas.
