I will pull quote from that same wiki
I'm hardly splitting hairs, your taking something yellow and calling it white. While we don't know if they are truly lucy (no pigment vs defective parts), but they at least look lucy. Many of the animals you posted don't even look it, then followed with...The stem leuc- is the Latin variant of leuk- from the Greek leukos meaning "white"
which is flat out untrue. I'm not even being technical. I think you will find your line is very lonesome.all of these are blue-eyed leucistics. they are not white, but all of them are legitimate BELs.
As for the pictures...
This results in either the entire surface (if all pigment cells fail to develop) or patches of body surface (if only a subset are defective) having a lack of cells capable of making pigment.
