We ended up applying camera-specific tone curves that match the embedded thumbnail after LibRaw has finished processing it. It seems to work pretty well. We took inspiration for that from how darktable does it. (darktable is open source so you can check the code if you're interested.) I'm guessing the variable contrast mode in FastRawViewer is doing something similar.

Good luck!
