    Why do DNG profiles vary based on exposure of chart?

      I made three exposures of the colorchecker, 1/2 stop difference, daylight 5600k.

       

      Then I used DNGPE to create profiles from each exposure. Single Illuminant, both tables, Adobe Standard base. These 3 profiles generate significantlly results when applied to any image. Why is that?

       

      Everything I've read says exposure of the colorchecker is not critical, as long as it is evenly lit and has no clipping. Not true in my case.

       

      Profiles generated from higher exposures increase saturation 5% to 15%, sometimes even clipping the red channel, and showing quite visible differences. Which profile is correct?
