A man who asks questions? <grin> (the mind boggles.) The only silly question is the one you don't ask. Once you have the Yamaha free of its swaddling clothes and restraints, it certainly will want a couple of tunings -- but sometimes I've found Yamaha's regulation is really good right out of the box. If so, it will want a little bit of regulation after being played in for a few months. Yamaha usually issues "service bonds" which have a list of things to check and go over. Be sure you're authorized to do the service bond work before you tuck into the piano's prep.
