I have a Canon DSLR with the option to enable/disable "highlight tone priority" (HTP). I'm somewhat unclear on just what HTP does, but my impression is that it improves dynamic range. I think this involves some hardware processing of how the photosites are interpreted. I think when it is enabled, this makes a difference for both RAW/CR2/DNG's and JPEG's.

I was wondering if this would matter enough to NI NR so that there should be a separate .dnp profile for when HTP is enabled or disabled?

Or is the effect rather subtle, and the same .dnp profiles can be used?

If I had such a camera in my hands, I would shot two versions of the Calibration Target in two modes of the camera, built two profiles and compared they noise levels, including those equalizer curves. That should help get the answer to the question.

I think the Auto Fine-Tune should be able to compensate for the differences in this case.

Might be interesting to check and compare, but I suspect that you are correct that AutoFineTune will compensate fine.
