I did a test with two separate RMD files to the same R3D clip. One with color science 2 and different ISO and Exposure than the one with color science 3. When selecting the color science 3 file, the image blinks a few times, indicates the setting is now "custom" but none of the values appear in source settings or in the bin metadata columns - not even exposure and ISO. This leads me to believe nothing is being applied. I am awaiting for official work from Avid as I reserve the right to be wrong. See attached files of the RMD XML for the color science 3 file and the result in the bin.
