It's a Rose
There have been previous threads about this - I've got a Rose Xeon, and it has similar makings - the result of the manufacturing process. You will find this on most matt UD carbon frames, from various brands. Here is a statement from Canyon in answer to someone who posted about this on Road CC.

Depending on the angle of the light shining on the frame, the appearance of this finish can change. This does not represent a flaw in the frame or its outer coating"
