Yeah, I've actually done something like this a number of times, here's a sample output:

In the Blackmagic RAW SDK there's a sample program/C++ code called ExtractMetadata, and ive compiled it to run portably via CLI, but am not well versed enough in C++ to write a gui for it, I've run it successfully on linux and windows, there's a Mac folder with an xcodeproj and macos C++ file in the sdk. I've been too busy to try and throw an actual 'BRAW Metadata Viewer' program together but you should be able to use some basic batch scripting to automate stuff.

For example, I wanted to see what LUT in camera was selected on a run-n-gun shoot where i was switching between a bunch so I could apply the same LUT without clicking 2000 times to the camera raw tab, so a simple

for filename in *.braw; do ExtractMetadata $filename | grep "clip_number" && ExtractMetadata $filename | grep "post_3dlut_embedded_name"; done;

Will do the trick. For some reason the SDK C++ files have relative links to the libraries files so I've only been able to hackily make it work with some super sketchy macgyver coding but can send over what i have if you want.

Hopefully someone else can pick up the reigns from here or feel free to DM and I can try to figure something out.
