If the subject profile is already selected and then the Media
selection switch is used, there is no update to the screen.
LC6X has a dynamic cache for the profiles on the system. Add one and
it's recognised without quitting and relaunching (nice when editing
scanner / camera profiles which are seen right away). Once the
preview is built based on the end-to-end calculation of a preprocess
LUT (individual intents aren't calculated stepwise but as a one-step
conversion for precision) then the media setting is also part of the
preprocess LUT. That is, there's no independent Absolute Colorimetric
intent in any profiles I've ever seen. AbsCol is calculated on the
fly from the XYZ values in the wtpt (white point) tag into the
Relative Colorimetric LUT. To rebuild the preprocess LUT after
visiting the media switch - chucking or checking in the wtpt info -
just scroll to the next output profile and back again right in the
image window.
