As a helper, I’ve used the mind blowing useful Colab in conjunction with the absolutely incredible Colour Science library. Technically this is one line in Colour, but I included the others to show what default matrices are used. It’s specification unless you tell Colour otherwise.
That’s one of the concerns that require addressing when choosing a reference space.
If you were targetting a ten ink print with a wider gamut, it would be a consideration. Gamut mapping via absolute or relative colorimetric, versus CAM or homebrew based perceptual / saturation might work or might not, depending. There’s plenty of room out there for clever folks like @anon41087856, and the way he’s been completely cutting to the core of image processing, to include tunable interfaces for pixel pushers to engage with their work with more control considering the output. Imagine a tunable gamut mapper? That’s pretty easy with the knowledge and coding abilities of the folks around here to have in Darktable almost overnight.
This isn’t a place where typical people have no control over the tools, and instead, sometimes magic happens as @anon41087856 has shown.
