Cryo'ing doesn't really change the molecular (crystalline) structure if the metal. It just causes them to pack more tightly, thus making better electrical contact.
Burn-in has a lot to do with "settling" the interface between the conductor(s) and the dielectric material. So I'm not sure how cryo would affect that. I would say a qualified "yes" but probably not as much as when the cable was new.
