Export for calibration

How do I export a RAW file for calibration, i. e. without any color and tone corrections? The result should be the same as:

dcraw -v -r 1 1 1 1 -o 0 -H 0 -T -6 -g 1 1 -W RAWFILE

Selecting “No ICM: sRGB output” will omit the ICC profile but still changes values: the image appears greenish as expected but has gamma corrected tones. With unsetting the working profile gamma to 1 the result as still to bright in comparison to dcraw.

Set all settings correctly, then under “Color > Color Management > Input Profile”, click on “Save Reference Image” which lets you save a 16 bit TIFF.
