i used to do this for a living (about 20 years ago) and we used to pride ourselves on trying to leave no trace of any drilling. it's probably almost impossible to completely disguise the holes but any decent company should be trying to be better at it than their competitor's.
we used to use various coloured powders/dyes to mix with the cement or in your case from what i can remember i would mix white paint with the cement and pick the stones up that were knocked out by the drilling and stick them in the wet cement.
hope this is of some help,
