Not just gmic although using Gimp that possibly the only way.
For example, these CLUT (cubic lookup tables) files https://www.shutterstock.com/blog/free-l...og-footage
You can use those .cubic LUT's in gmic. I suspect that they might already be included in the very extensive collections that come with gmic Colours > Color Presets filter.
