That's not surprising, because that one is mimicking the Canon "Standard" JPG style out of the camera, which is definitely more contrasty than a flatter RAW (which is what DT normally aims for). > With the first one everything looks fine.

I guess it depends what your subject is because I noticed quite a strong change in the deep blues. I'm thinking this .icc sounds like a good option for replacing the built-in enhanced colour matrix, though I understand that the dt devs are actually going to be changing the default matrix back to the standard color matrix, at least in master, so I'm not sure this one will ever make it into dt.
