All CMS systems I have ever seen know how to take a given XYZ value and turn it into an exact value to put into the display hardware. Therefore there is a fixed, never changing, conversion from sRGB to the display (unless you change the cms settings of the display, but if it is correctly calibrated why should you do that?)

Um... every reference I've read on the subject says that displays can and do change over time, and need to be periodically re-mesured.
