MAF vanes and screen moderately dirty/sooty on the hot side. Normal? If not, what could cause this?

I would say that it's not overly sooty, but there's a thin film of black soot on both the vanes and the screen. Could it be fuel blowback (and is this even possible)? Is this a problem? I doubt it is, but just checking.
FYI, I have a Hyperboost adjustable DV.
Thanks.
