10bit Linear DPX Export

Hi-

I am working with 2K source material which is 10bit linear DPX, and am looking to export back out to the same color space.

I have made a pretty careful study of the DPX export settings. Is there any way to know if my export is linear or log? Or to specify it in AME? MediaInfo confirms that the source material is indeed linear. When I inspect the 10bit DPX output file with MediaInfo, it doesn't say either way (linear or log), and would like to have some confirmation that I am hitting my customer's spec.

Thanks-

- John
