By correct aspect ratio you mean 1.66:1? Criterion’s decision to use that aspect ratio was initially controversial but they provided documents backing it up.
I do indeed refer to 1.66:1.

The old Blu was 1.78:1.
Yes, I know. 😃
There’s a scene in Filmworker, the 2017 documentary about Leon Vitali’s relationship with Kubrick, where Vitali is ranting at Warner Brothers for using the latter aspect ratio.
