How Could I extract HDR gain Map from iPhone's Heic?

Question

with jpeg format, I know can use:

exiftool -b -MPImage2 test-lumen.jpg > depthMap.jpg

But if the format is Heic, there is any method can export the HDR gain Map?

You can install (libheif) and do:

heif-convert <source_file>.HEIC <result_file>.jpg

It will save auxiliary images as well.

You need to be able to extract Apple specific metadata first.
