If by unique weapons you mean weapons upgraded through twinkling titanite, that's not quite true as the silver knight sword is enchantable despite using twinkling titanite. If by unique weapons you mean weapons that can be obtained only once per playthrough that's not quite true as many unique weapons (such as the great scythe and the mailbreaker) can be enchanted.

The only boss soul weapon that can be buffed is the Dragon Bone Fist.
