Creating wider gamut G'MIC Color Presets?

@Teto

Besides, I did a test with a poor 3D-Lut (like 8x8x8) and a big one. Then I opened the 2 results as layer with gimp, and the above layer was set to “difference”. And yeah you see them.

With so low definition (8x8x8), indeed, you can see a serious difference with normal ones. But between 48x48x48 and 63x63x63 ? Really ?
Of course, 63x63x63, or even more, doesn’t hurt if your hardware supports it !
Dt supports 256x256x256 LUTs.

@afre

One little idea from me is that G’MIC interpolates its CLUTs, so, in a way, narrow becomes wide

Sorry, I’m not sure to understand what you mean there but that doesn’t seem to be related to gamut width…
Anyway, I have myself transformed LUTs to compressed LUTs using GMIC command line (not sure this is still available, but that was a quite long process). With my not so young eyes I could not see any difference between the produced images (at least above of 33x33x33).
