They reuse a bunch of the dry dock scenes in Wrath of Khan. I explored using them for my HD director’s cut recreation, but unfortunately most all of them are trimmed compared to their length in TMP.
The behind the scenes documentary on the bluray shows the transfer before the DNR and contrast boost, although it still unfortunately doesn’t include any full shots.
Comparing Synnöve’s sample to that footage shows really great results, detail-wise: https://i.imgur.com/pIA2sv2.png
This process is basically magic as far as I’m concerned.
