Creating wider gamut G'MIC Color Presets?

Thank you all for your replies!

If you use a hadclut built for sRGB I think you could try to convert the file (which is an image) to Adobe RGB to get a new hadclut working in Adobe RGB. That should work. Am I wrong ?

I was thinking that this wouldn’t work as the gamut is sRGB and the conversion won’t automagically expand the gamut beyond the source space? I’m not sure though, this is more of a question. If I want to try this, should I assign the sRGB profile to the .png and then convert to Adobe RGB? Sorry, that may be Photoshop lingo. Not sure how I’d do it with free tools. Guess there’s a way in ImageMagick or G’MIC?

I’m reading the quote below as a sign that it won’t make the gamut any wider?

I’m afraid you cannot increase the level of information contained in the LUT.

@Teto

there’s a free one, that I tested and seems good, in my opinion, GrossGrade

That’s a very nice find, thank you! Seems at least the beta will be free. I’ve been wanting to try 3D Lut Creator for some time. Russian software just like GrossGrade.

Yeah, read it some year ago. Perhaps I should give it another read.
