Sorry for the typo. When comparing the presets, please pay attention to these areas: In the SMPTE color bar pattern: The small gray patch inside the black area below the color bars shows a visible difference between the native preset and the recreated preset. In the BarsAndBlack_16bit.TIFF pattern: The last few grayscale patches on the right side of the grayscale bar show different luminance levels, especially in the near-black region.
