Creating wider gamut G'MIC Color Presets?

Accuracy
I’m afraid you cannot increase the level of information contained in the LUT.
The precision depends on the size of cube and of the numbers themselves. Most of the halcluts are 8 bits but some of them are 16 bits.
However any transformation of the cube at constant size will tend to decrease the accuracy.

I realize I still have questions The G’MIC Color Presets are available from gmic.eu or rawpedia.rawtherapee.com. Those from gmic.eu are routinely updated (last update 2021-05-14) but are “only” 512x512 px. Those from rawtherapee.com are 1728x1728 px, but they were last updated 2015-09-20.

Are the 1728x1728 px ones from rawtherapee.com necessarily better, or should I go for those more recently updated?
