Albinism is the lack of pigment (melanin) and melanistic is an increased amount of black pigmentation. These are the literal definitions.
That's true, but a darker colour scheme
is present on Melanistics - just as a lighter colour scheme
is present on Albinos. While most animals with albinism have white fur and red eyes - that's not always the case. A good example is in humans. The melanin in the eyes of a human with albinism generally makes their eyes blue (with the occassional red tint to the pupil). Thus, it doesn't seem too much of a stretch to believe that Pokemon - who, lets face it, don't exactly obey biology anyway - would simply be a lighter, somewhat different variation.
Incidentally, I'd also say that 'shiny' Pokemon aren't exactly... well, shiny. If I were to get out a shining-brush and start polishing a charizard then it wouldn't turn into a shiny charizard. It would certainly be a charizard that is shiny (in the literal sense), but it wouldn't be a
shiny Charizard.
If word definitions are the problem, we'd have to re-work almost all of Pokemon. 'Mega' means very large - but Mega-Evolved Pokemon don't usually geta lot bigger. That's associated with Gigantimax Pokemon. Similarly, a totem animal is usually worshipped and/or used for symbolism - but I'm pretty sure the Totem Pokemon aren't worshipped by the alolan culture (don't quote me on that one it's been a while since I played S/M/US/UM).
TL;DR - Pokemon already bends words & reality to an extreme. It seems odd that PFQ should be any different. Either way, that's just my 10 cents/pence/credits/other-currencies-are-avaliable.
