Colt Box After Factory Work?

I have a 1976 Peacemaker Buntline that was reblued & recased by Colt to factory specifications in 1990. When it was returned, it was sent back to me in one of their 1986 anniversary pattern “Heritage of Colt Craftsmanship” boxes. Since the paperwork documents the date of that work, should I worry about hunting up a box from 1976?
