plant-i.d. Need a hand identifying and caring for Mystery Christmas Fajita.

I was gifted an unknown chilli plant earlier in the month. I've been told that it's "probably a hot fajita chilli". I haven't grown anything of this kind before, but I've been given chillis of a similar description in the past, and none of them were shaped like this or as large, and these ones definitely have more of a sting to them. They seem to go into a yellowy-green brown, before maturing into a red, rather than having a stage of being particularly orange.

So, what's the consensus? Fajita or not? And are the spots on the leaves a cause for concern?

is it the light or do the peppers look yellow?

Definitely mostly green, the lighting and camera makes it more yellow. But the yellow is there, maybe 70% green, 30% yellow. Here's the same chilli today. It's hard to pick up on with the lighting, but it's starting to get a redish-brown tinge to parts of it.

My bad. It seems they do turn orange for a time, it's just the earlier ones matured so quickly that it was barely visible.
