It probably depends on population, whether or not the feature breeds true, and how different the the mutant varient is from a normal one.

For instance,  a blue oni would give birth only to blue oni's so the would be counted as a seperate species from a red oni. They would also have a sufficiently large population to be a culture and race in amd of themselves. Hobgoblins have major differences that seperate them from normal goblins, intelligence  (or lack there of), strength, a lack of coordination, and most importantly of all... the breasts (which in a universe that largely revolves around sex would very important). Where as a submissive dark elf wouldn't be garanteed to give birth to another submissive dark elf, would have too small of a population to become a seperate culture and wouldn't be too different from a normal dark elf.
