Yes, I think it's affecting the profile, but if the image itself looks as you expect, it's only a problem if you're worried about the blue in the white surrounds.
I don't know why it's printing the blue for sure, but if it is the same issue that we came across, then it seems to be because the OBs are not being UV filtered and so white isn't white - it's moved towards UV. That's a guess. There are far more knowledgeable and qualified people on the subject on these boards (like Andrew), and I'm just assuming you're seeing the same thing we saw. But as a general understanding of what's going on, that's mine :-)
At the end of the day, if the prints look right, then that's the most important thing.
