If I may note, watch the T2 making of for the opening scenes in the biker's bar.

Those scenes in 1991 were color timed blue as they appear in this making of (it was edited prior to the film release), however, since laserdisc and DVD and Blu-ray, the scene is now warm orange brown.

I feel any "restoration" project should get those scenes back to the theatrical colors they had originally.

That means nothing, edited before release means more than likely the wrong timing.

I agree there are issues with colour and personally sound
