Probably won't affect a thing regarding playback. It's in the vinyl as far as I can tell. If the grooves look normal, you have nothing to worry about audible wise.
I have a little of it on a white vinyl Rolling Stones re-release I got recently. Not nearly as much as that. Didn't affect the sound at all though. In fact the vinyl was very quiet.
The vat holdiing the vinyl might have been contaminated (or not cleaned thoroughly enough). I remember this on some of the white Crystal Clear pressings I had from the early 80's. It should not affect the sound.
Thanks for the replies guys! I'm going to hold off on cleaning/playing it until I hear back from Warner Bros (reprise). I'm hoping they can send me a replacement. I just thoroughly inspected all 3 discs in natural light and there is indeed some of the same on Disc 2 and 3, but very minor in comparison.
