Not sure how worth mentioning it is considering how good the overall write up is.

Even though the human visual system has a non-linear perception of luminance. The camera data needs to be adjusted because the display has a non-linear response. The camera data is adjusted to make sure it appears linear to the displays face. So it’s display non-uniform response that is being corrected, not the human visual system.

There is a bunch more that can be done and described.
