The new 4K remaster of Batman (1989) has replaced the original sound effects with new modern ones which makes for a somewhat distracting experience for some viewers. The original mix is NOT included on the 4K disc. Also it looks like the color grading was tweaked to include a fresh new teal look.

This 2-Disc Special Edition DVD has the Original DTS Mix not found on the blu-ray or the 4K releases.
Syncing the original DTS mix from the old 2-disc special edition DVD would solve the SFX revisions but it looks like the teal is here to stay.
