Here is the official Fender Custom Colo(u)r Chart :
Original Olympic White looks very white as there is a blue undercoat, which is a well-known trick to make white looks whiter. This blue dye trick is also used in xerox paper, cloth, washing powder, laundry detergent, photographic paper, ...
When agic, all (nitro)cellulosic paints tend to become creamier, which is especially the case with the Olympic White.
Modern Olympic White is a recreation of this aging process, so absolutely not a reference.
