I think Wrath of Khan looks pretty close to the theatrical color timing i can only find on the first issue laserdisc before the BD.

But since they were working from the OCN which was badly faded or damaged its not perfect.

The DNR of Lowry though is intolerable but not as bad as say star trek III or IV.

I and VI were older transfers with the dnr already applied sadly.

Star Trek I and VI i feel are in need of a restoration.

Not that star trek I is particularly bad on blu ray the transfer was phenomenal but i feel it could have been better with the newest HD scanning tech.
