Could be missing something but I'm pretty sure this is a bug.
I'm running Ubuntu and version 12.40 of exiftool
Here's what I get from running exiftool Caseandtarget.dng
Black Level : 40 20 0
but the actual blackpoint is 4,097
and here's a link (https://mega.nz/file/Ho5BhBAR#-JjM557JtMnw6-nZ7_JQIeMAR-lngndofGhnLlps7tg) to the .dng
> exiftool Caseandtarget.dng -subfiletype -blacklevel -G1 -a
[IFD0] Subfile Type : Reduced-resolution image
[SubIFD] Subfile Type : Full-resolution image
[SubIFD1] Subfile Type : Reduced-resolution image
[SubIFD2] Subfile Type : Reduced-resolution image
[SubIFD3] Subfile Type : Reduced-resolution image
[SubIFD] Black Level : 4097 4097 4097
[SubIFD3] Black Level : 40 20 0
There are multiple BlackLevel tags in this file. I think you are interested in SubIFD:BlackLevel.

Use -a to show duplicate tags:
exiftool -a -G1 -s Caseandtarget.dng
[...]
[SubIFD] BlackLevel : 4097 4097 4097
[...]
[SubIFD3] BlackLevel : 40 20 0
[...]

Awesome!
Totally makes sense. Not sure why that didn't occur to me.
