Originally created by @Feathered-Serpent on GitHub (Mar 26, 2024).

Movie: Sonic the Hedgehog 2 (which features a normal BluRay and the UHD in the package)

The movie features Bus Encryption, but I also opened the disc in MakeMKV prior scanning to enable LibreDrive which bypasses the Bus Encryption for other tools then. Also no result without removing the Bus Encryption.

BluRay:
MakeMKV: AACS v68
DVDfab: AACS protection (AACSLA) (MKBv68)

Can you either upload the .inf file here or copy the contents? I'm wondering if it's laid out differently

As it is a binary file, I attached it.

MKB_RO.zip

Comparing it with the normal MKB_RO from the standard BluRay, it seems there are just some changed bytes, probably for AACS2.0:
BluRay (last byte translates to dec 68):
grafik

UHD (last byte translates to dec 76):
grafik

PS:
not sure, if this document can help for anything AACS related:
