Min / Max point on colormap is not representative to surface.
This point will "nearly" always be on the surface edge!
And this value is used when you evaluate Profile surface dimension.
If you take a look at pictures below and special on the colormap / colormap scale. 99 percent of this surface is green and orange. The Profile surface dimension value should be around 0.5 but it is 0.756 (ASME).
This because of what I believe error from the scanner.
Different ways to solve this could be:
Let the Min / Max be on a colormap "area" and not as a point.
Or an outlier filter...
