What color parameters can be controlled by pixel maps?

I believe any typical RGB/CYM color mixing attribute can be controlled. Some attributes like UV and perhaps a white parameter might be excluded. Beyond that, what is also excluded is non-mixing parameters such as a color wheel or color-macro parameter. Other things that might impact color such as a CTO or CTB flag, diffusion, etc.  

I can't find the video, but I believe this was discussed in an ETC Study Hall video during the pandemic. If I recall correctly, it uses the CIE backend that the color picker uses, so in theory anything you could control in the CIE color picker you should be able to control in the pixel map.
