The thing about that is, though, is the makeup and dots on Bill's face were put there because ILM didn't know how well they'd pull off the CG and wanted something to fall back on, but in the end, they didn't use any facial motion capture and didn't even use Bill's real eyes like they thought they might need to do. They hand-animated all the expressions and lip-synch.
So, in terms of how much of the actor was pulled from mocap, it's about the same as Gollum was.
