When converting dng file to jpeg file, jpeg file is generated with color discrepancy

[mohanrajams]

Describe the bug

The dng file has embedded adobe xmp, when we try to convert to jpeg the color is not applied properly (white balance I guess)

I am not able to attach dng file , however I have attached extracted xmp file

I want to know

1. Whether the xmp from adob is supported by darktable
2. If not supported is there a way to convert adobe xmp to darktable xmp (are there any tools available?)

Steps to reproduce

1. Extract xmp file using exiftool (exiftool -xmp -b sample_file_to_investigate.dng > sample_file_to_investigate.xmp)
2. use the extracted xmp file with darktable-cli ( darktable-cli sample_file_to_investigate.dng sample_file_to_investigate.xmp sample_file_to_investigate_newdarktable.jpeg)

sample_file_to_investigate_xmp.txt

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip

Did you read https://darktable-org.github.io/dtdocs/en/overview/sidecar-files/sidecar-import/ ?
The related code is old and has not been maintained for some time. You should not expect much...

I assume that the Adobe xmp comes from Lightroom. Darktable isn't compatible with Lightroom processing, so that will never work as you seem to think. And while there is some support for converting certain LR operations to the rough DT equivalent, that code is really old and broken, and I'm not sure it ever worked with darktable-cli.

Embedded metadata for dt must be "standard" exif tags supported by exiv2 so (unfortunately for you) only those are read by dt and possibly processed.
