Adywan used the GOUT when he had to, but actually reinserted high res scans of the original matte paintings when possible.
Or so I've heard.
He did this for the Falcon Cloud City landing pad BGs, the Leia's waiting room matte, and possibly for some of the other Cloud City establishers, IIRC. He also filtered the GOUT portions, and used blending/morphing techniques to segue in and out of GOUT footage at times.
