The xenons on my current one are the adaptive steering type, really good I find. My old Subaru Forester I had previously was really good, the CX5 is slightly better. Will be getting the new version with LEDs in about 4 weeks, so will have to do a comparison.
I would imagine that the DRLs dim as I think that's a requirement under the construction and use regulations, but don't know for sure.
