The color accuracy of all digital cameras today is a Chimera

As I discovered when copying paintings by artists of the 19th and 20th centuries (this was my work), no digital camera can convey the exact color.

Would have been more interesting with a Foveon camera tested, and even Provia film. I would have thought there is better colour accuracy using a filtered RGB or monochrome sensor and then recombining the images. Most cameras are just using Sony sensors nowadays, so the results shouldn't be too different and without any explanation, then maybe the differences actually come down to the image processor in each camera.

Given the importance of the task, isn't there any commercial-\industrial-grade archival scanner that prioritises colour accuracy?

I read the article below in the past. It may give better idea for those who will use the camera for color critical works. I think a lens with good sharpness and minimum chromatic aberrations is perfected.

"I think a lens with good sharpness and minimum chromatic aberrations is perfected."

As far as I remember, there is a numbers that all lenses must follow: 11-0-0. Deviations from these values indicate whether the lens will give a warm or cold shade.

Not exactly but closely related, it reminded of this article I read recently: https://www.imaging-resource.com/news/2020/08/18/fujifilm-film-simulations-definitive-guide
