Picture style: portrait -> Linux Raw

Hi,
I am struggling to get popping color that are showing on my jpeg part of the raw+JPEG duo file under Linux.

A lot of the pictures are fine with no modification, but sometime I just want to boost a bit the exposition, or do another "raw manipulation". In almost all cases, I end up with duller colors after I do that since the starting point in raw is usually miles away from the jpeg output.

I so far tried photivo, darktable, ufraw. My camera (5D) is currently set to picture style: portrait.

I am most likely the problem in this situation, but my hope is to get a preset file that will get me the config that were used to produce the JPEG in any of the above mentioned software.

I've checked many youtube post processing "tutorial", but nothing so far helped me getting those popping color and realistic skin tone, without making it look fake.

Any help would be appreciated.

You might be able to run DPP via an emulator? That's the only way you're likely to get an exact starting point of your chosen picture style as it's only Canon software that understands the picture style settings. Other RAW converters provide their default starting points only.
A close approximation is to use Adobe's camera calibration selections in Lightroom or ACR... Not tried to get those to run on Linux though.
