i find this supremely interesting as well because i do think that what you have outlined is generally true but not always eg: yes, my regular albino dwarf burm would standout and be more susceptible to predation during her early stages *however* i would argue that my granite mainland Burm is even *more* adapted to camouflaging comparative to normal types - would be an interesting thing to field study ngl but to that end i think that also brings into question what i said about re-examining how we think of “captivity” insomuch as it is or can be an idyllic form of nature with special benefits eg: perfect consistent weather, no chance of predation, etc - technically you could say that’s “unnatural” but i would argue that it is and it is not
but with that said - i don’t think that characterization of albinos as being “unnatural” is something i would agree with because they are, objectively, naturally occurring they’re just not always successful - which technically, that could be said of normals too - i would argue the “unnatural” designation should apply to artificially created/line bred morphs like “scaleless anything”
