XP-L Dome -orange peel?

Has anyone else noticed, the XP-L has a slight orange peel on the dome? The first few times I noticed it, I thought it was a smudge or a fingerprint…but they all have a slight orange peel on the curved surface. The 4 flat sides are still clear.

All the XP-Ls I’ve seen have that so it’s probably just part of the manufacturing process.
