Yes, bugged. And I don't say this only because ZOS has stated that they only change the appearance of things already in game unless there's a visual bug, but because it's genuinely a visual bug. There's absolutely no reason why the paleness layer should be above face and body markings. When my character (theoretically) puts on black lip dye in the morning, why would the black substance suddenly turn pale gray just because she's a vampire? Here's an example:
how it looks in game (left) vs. how it should look, after image editing (right)
It seems like common sense and something that should have been done with Greymoor, you know, the chapter that focuses on *vampires*. Besides, the fix is probably as simple as editing the vampirerace properties like in Skyrim's Creation Kit that would only take 30 seconds to do and could be packaged in an incremental update. Or, I don't know, rearranging skin overlays to put the vampire layer near the bottom which would take an equally short amount of time.
Refusing to fix this is consumer unfriendly as well. I bought the face markings pack from the crown store so I can customize my character's face freely, but now that I'm a vampire, I'm not getting what I paid for here. All the markings, face and body, are washed out, ugly and, in some cases, practically invisible.
I mean, come on. 7 years and no one has had the time to fix this? There's a mountain of things people have been asking for for years which take no time to fix at all. Rather than spending the resources to make another costume to put in crates, separate a team from the main body of designers for a few weeks and dedicate them to fixing these issues, which can be fixed in the same amount of time it takes to registry edit some internal setting on windows.
And as a sort of side note, a close friend of mine, who's a diehard Elder Scrolls fan, refuses to play this game because, in her words, "It's not an elder scrolls game". She can't identify a bug and boot up the creation kit to fix it. She would have to wait, helplessly, for the developers to (never) fix the bug.
