The "extreme" Hondurans are T positive albinos,without any doubt.(IMHO)The fact that another form of T positive albinism in a completely unrelated species was originally produced in the described manner,and seems to be inherited,and expressed in a different way,does not disprove the obvious conclusions drawn in the case of the Hondurans. Hypomelanism & Tyrosinase positive albinism are often misinterpreted initially ...a good rule of thumb that usually holds true across species borders,is: hypomelanism results in a reduction of black pigment,which often allows other colors normally present to appear "brighter",but black is still "black",whereas Tyrosinase positive albino examples show normally black areas as purple/purplish grey/grey,because of a biochemical defect the animal cannot complete the nesseccary steps needed for the final stage of "black".
