I don't think the WoW does anything to the colored parts - it doesn't bleach the fur. I've been using it (or the equivalent, there are a lot of "blue shampoos" out there) for years on legs and ruffs before shows, and haven't seen a need to be careful to keep it off the sable fur.
of course, why don't you ask me about the time I tried to use white minx directly on the slightly-yellowed parts of a ruff the night before a show...The poor dog came out looking like a little old lady with blue hair! I managed to get most of it out, but she still had a, um, bluish cast the next day. Mom was not happy!
I suppose there's no photographic evidence?

then it didn't happen
