Not in my opinion. Depends what you consider messing up the bark. If you are looking for dry crunchy bark then yes, I guess so. It does not cause the bark to rub off though if that is what you mean.Does the sous vide hold mess up the bark?
I will describe it this way... it comes out pretty much exactly the same as a tallow soaked paper wrapped brisket. That makes sense though when you think about it, because the suction from the vac seal will pull a small amount of the naturally rendered fat out of the brisket, coating the exterior, and as such it is basically a tallow soaked brisket, just in a vac seal bag rather than a paper wrap.
Here is a picture of when I did a while back...
