I think Raw Therapee and DarkTable use the same library for dealing with different cameras. Since I have Olympus TG-5 and Panasonic Lumix G80, I would like to know what is needed to complete the support for them.
I can see from the Darktable website that they are not yet fully supported (https://www.darktable.org/resources/camera-support/). Even though there is a ticket for Darktable saying the TG-5 support should have been added in 2.4.0 milestone.
I am available to provide info on the camera or specific samples as needed.
