Yeah, it counts. Evolution is simply a shift in the genetic makeup of a population - it doesn’t have to include the introduction of new genetic variants, just a change in the frequency of existing variants measured over the population as a whole is sufficient.

One can argue the point.

You do note that I suggest there may have been no change to the genome at all, just a change in its expression due to environmental triggers.

And it hardly gets interesting until it’s gone far enough to create a new species, defined as no longer able to breed with the original (esp if the original dies out!). Even most creationists grant minor variations.
