TBH the odd occasion I've done a CAT III B No DH landing as captain ( and I've done it on the 744 and the 777) my attention has been glued to the PFD ( especially the raw G/S and especially the raw Loc )right down until probably 60 knots or less.. I was sure as heck not looking up at "zero" or immediately thereafter for lights or grass if all the other annunciations were normal.
