They also sell rare animals with 0% fertility chance, or animals that are very very old and are not going to live any time at all.
While it stinks, it's just part of life and one needs to read to protect themselves and pay attention.
That being said, having the icon show an albino if it actually is makes complete common sense and should be made to work as such. Have you seen an actual albino on the market? Maybe it does work that way and you haven't seen it? I just haven't seen one on the market myself is why I ask. Heck, while they are doing this why not add an "albino" filter option to the page too.
