Thinking out loud, I think the governing aspect of this is fidelity. Cover bands, and impressionist are always going to be delta away from the original. Current-gen replicas can pass the generic test of "is this indistinguishable from the original by laymen?". This gets especially messy with movie actors. Specifically -several extremely high-profile movie actors _specialize_ in the sort of roles they take to project a certain persona, and be _the_ guy for that role. It's also known within producer circles, that a single actor can move the sales needle +-~$X0M revenues; which is part of their valueprop. Present-gen replica tech poses an existential risk both for brand building, and exclusivity of these actors.
