Not sure if I read somewhere that Pioneer dumps would not work, but I created both, one from the LG drive and on from the Pioneer drive.
You read correctly

. The Powers That KEYDB cannot read some of a TGZ dump file's metadata if that dump was created using a Pioneer drive. Another problem can be if MakeMKV has truncated the
AACS/MKB_RO.inf file inside the TGZ dump file to only 56 bytes, which makes it unusable for KEYDB. This other problem can happen with any UHD drive, not just Pioneers. However, sometimes multiple different disks can use the same
AACS/MKB_RO.inf file, which means that it
might not be insurmountable.
Also, you might find
SamuriHL's tool useful.
