did you say before that gimp's CMM was 8bit?


Yes, it's to my very knowledge .

8bit encompasses the visual range of colors, but processing, to meet
Nyquist would be 16bit or higher


That's not a frequency, so it's not related to *Nyquist*. But yes,
depending on the steep of the tone mapping curves, you might get banding
(quantization artifacts) due to the limitation of the resolution.
