Would that theoretically mean that using -S AdobeRGB1998.icc in colprof should
deliver the same result for:
1) Conversions using Relative + BPC
2) Conversions using Perceptual
(for example converted in Photoshop using Adobe (ACE) with selectable Black
Point Compensation)
I don't get the same result, what kind of -T parameter could give me the same
conversion result in Perceptual as a Relative + BPC conversion, if there is any?
Best regards,
