From what I'm reading it's a completely separate recessive gene. The homozygous animals for this "false axanthic" (not sure it has a name) no longer look axanthic after a shed or two but when combined with albino makes the low contrast older animal. Your female albino being high contrast would indicate she is not homozygous for this 2nd gene like your male. Still some chance she is a het as it seems to be in some albino lines so you might produce some snow looking babies that will quickly look like normal albinos but then grow up like dad with the yellow on yellow or she might not carry the gene at all and produce all normal looking albino hatchlings.
