These specific masters have never been shown in HD anywhere as far as I know. It’s up for debate how accurate any of them were in regards to color. The Shining’s DVD does not even have its original theatrical blue ending credits.
Honestly the best way to watch these is either the boxset DVDs themselves or syncing their mono audio to the UHD releases. The Shining and Full Metal Jacket have DVD mono syncs already. 2001’s UHD comes with its original audio intact. Color-wise the UHD releases look fabulous and are probably as close as we’ll get to original intent.
I wouldn’t say “theatrical” blue credits for The Shining cause there’s no absolute proof that they were blue in theaters
Yes there was an ABC broadcast that had the end credits in blue but who’s to know if they weren’t made blue for the broadcast or it was an error when creating the TV master?
