Camera calibration tool concept

Hi all.
The question is more out of curiosity than to solve a problem.
Many people are familiar with the camera calibration tool and how this tool works.
But. At first glance, you might think that the tool is similar to the channel mixer tool in Photoshop, but this is not the case.

The channel mixer either compresses or decompresses the saturation of one of the channels, and the camera calibration tool compresses or decompresses the saturation of all channels, based on only one of them, as I understand it.
That is, if we try to compress the saturation in the blue channel in the channel mixer, we will simply see a lack of variability between blue and yellow colors. And, if we remove the saturation in the blue channel, in the camera calibration tool, we will see how the overall saturation changes.

Is it possible in the channel mixer tool to simulate the behavior of the camera calibration tool? That is, what logic should be followed? Well, or what is the principle of operation of the camera calibration tool? Can someone break down and explain this process?

Thank you. Really.


All links describe how the tool works and how it differs from other tools. But... the question was about how to reproduce this approach using a channel mixer, or similar tools.
Example. I work in Adobe Premiere and want to replicate the camera calibration tool in it. Let it not be Adobe Premiere, but Davinci Resolve - it doesn’t matter. Even photoshop.
