The models look perfect as they are. They look as good today as they did back then. Something that can;t be said for the CG models in the prequels.
There are plenty of ships in the PT that were real physical models, you know.

In fact, the PT had more sets and models than the entire OT. But they still had to use CGI because some things were impossible to make without it. And that’s not a bad thing.
Yawn…this old argument again.
Only TPM has physical models used for ships/ vehicles. For the other two they were purely CG.
And that “The prequels had more models built than the OT” defence falls flat on its face when you take into account that the OT used real locations, full scale sets or partial with matte paintings, instead of many sets & locations being built as miniatures and the actors filmed against greenscreen or the minimal amount of set piece. ROTS doesn’t have a single outdoor location shot in the entire movie. It was filmed entirely on a soundstage, which is why the outdoor scenes look incredibly fake.
