The part is going to come out EXACTLY the same as the surface it is in contact with. If you're putting a perforated release film on it, it's going to come out with the perforations, and likely not much gloss as those films don't tend to be glossy. As well as any creases you are getting from the bag, which tends to be inevitable given that is how you get the vacuum bag to conform to inside radii.
You could try to use a non-perforated release film like FEP or mylar release film, which will give you a good finish provided you can get any and all creases and voids out. In all honesty though, I have never had excellent results trying to get a good finish like that. There's nothing wrong with using vacuum to hold the carbon in place on complex parts, but it's less frustrating to just accept that you are still going to have to do some finishing work on the part. As long as you don't pinch the carbon in the bag, then it shouldn't take much just to sand it flat and then clear coat the parts.
