Beginning with version "Feb. 16, 2024 - Version 12.77", exiftool can decode some of the DPRAW tool edits saved in a recipe file by Canon DPP software. In DPP, I often save a recipe for a record of the edits I have done and then I can use exiftool to display that history later. https://exiftool.org/ Exiftool is free software.
For example:
exiftool -s -G0:2 IMG_9108.dr4
