Can't give you the answer to this but here is a UK ATC view.
First, the vv001 is not a cloud ceiling value but a vertical visibility, which implies that there is no measurable ceiling. Second, ATC does not concern itself about what minima the pilot may need (although most controllers have a pretty good idea of CAT I minima) but rather tells the pilot what the conditions are and then will ask for the pilot's intentions, i.e. pilot makes the decision and ATC will do whatever it can to accommodate the pilot's wishes.
Hope this is some help.
