I'm saying you can't apply that to the prequels because all the major actors that weren't weren't CGI / masked were established actors.
Between making a New Hope and Attack of the Clones Star Wars and George Lucas got famous. Then they could hire all these well-known actors. Perhaps other actors knew it was a kiss of death to perform. Perhaps Lucas knew and didn't want to do that. Perhaps they just preferred having reliably good actors in their movie.
