One thing the Team -1 version makes very clear is that the special effects shots were considerably grainier than the rest.

Yes, all optical effects shots have additional layers of grain (including the optical wipes) - some more than others. A true restoration would de-grain the entire film, correct all the dirt and scratches, and then re-grain scene by scene. That goes way beyond what Harmy's version is capable of delivering. You also may want to reduce the overall grain one generation (since this comes off a print).
