I was very impressed how many color information present in RAW files compare to ProRes. Even if you lower saturation to 0.1 in Secondaries Color Corrector, you are still able to recover colors from RAW image.
P.S. You can get visually same result from ProRes files if set Saturation to 4.0
P.P.S. ProRes samples converted from RAW file in BMDfilm gamut/BMDfilm Log gamma
