easily could be utter chaos. I had a colony that I banked with my friend and the looked exactly like that under her power compacts. Give it some time, I'd say you have a good chance that they'll morph back to what everyone else thinks when they hear utter chaos zoas.
My utter chaos colony has polyps that look similar to those on the top of the rock where exposed to the brighter light, more pink/orange with very little black. On the side they are much larger with more speckling like you'd expect.
They definitely seem to take on different characteristics based on even subtle differences in lighting.
