They do have a strong resemblance to bowsers, though if not lineaged in some way to the original namer, they should not be called that.
I don't know about the OP's being 5 colors, but the picture on coralpedia does also look very similar. I have 5 colors from a few different reputable sources, and I do not think they look the same as the bowsers and first pic. Mine all have the green centers and a golden/orange ring, but the outer rim is more of a pink to sometimes purple color, depending on lighting. They've never appeared burgundy like the ones posted here.
If there are people with CAR's that look just like that, I would question the lineage and if the are true CARs. I've had CARs for some time and in many different lighting and water conditions situations and they never look that different. The intensity of the red may change, but they always have green centers with a deep metallic red rim and skirt with no median color between the green and red.
