With all of the original founder animal sources/localities that started these albino projects, many listings will say for example "Nicaraguan T+ albino", "Costa Rican T+ albino", etc. This does not inherently mean that the animals are pure locality examples of these mutations. Rather it simply means that these are the particular strains of albinism carried by those animals, and is not a guaranteed representation of their lineage and locality unless that can be honestly and reliably provided by the breeder
Similar with examples of motley boas listed as Colombian Motley. That simply means it is the Motley mutation that was originally produced from boas of colombian origin as opposed to motley boas of Argentine origin. A Colombian Kahl or Sharp albino is not a guarantee of pure, non outcrossed, colombian lineage. Rather it is an example of that trait which originated in colombian boas and was subsequently bred to everything with a cloaca to produce more of them.
Mind sharing who you acquired your boas from? This will help to provide insights.
