Insulation with black on faced side?

I recently had my attic insulated with R38c, but i noticed that a lot of batts were almost like burned on the face side? Has anybody seen this before? I have attached a picture. They were like that when we bought them in the package? there were only a few of them. Is that mold?

Doubt that's mould...bitumen-based vapour retarder material showing through the kraft more like it...

I agree with ccarlisle. I would be more concerned to block the attic space air at the rafter bays over and under the knee walls. And where the rafters step in elevation:
And the air space gap between the insulation face paper/drywall back, and inside stapling:

Did you install baffles over the all the cathedral ceilings? I don’t see one in the closest bay of near rafters in attic.(Could be my eyes,LOL) You left the paper on the batts in the attic (fire code violation) but didn’t run the ceiling insulation all the way down? Yet you insulated the knee walls. Is this a conditioned attic or vented?

Be safe, Gary
