first off those pictures are awesome. that is mainly where my strain is as well. that and around my eyes. Where my eyelids meet my eyes. Also, my discomfort is not constant. its only when things change on the screen. scrolling and popping up new windows mainly.
minor discomfort is a big discomfort when working with software i have experienced.
These two sites were insightful for me:
I past the following to save the click:
"The best way to get profiles is to generate them yourself, although this does require some initial outlay.
Many manufacturers do try to provide color profiles for devices, although sometimes they are wrapped up in driver bundles which you may need to download, extract and then search for the color profiles.
Some manufacturers do not provide accurate profiles for the hardware and the profiles are best avoided. A good clue is to download the profile, and if the creation date is more than a year before the date you bought the device then it's likely dummy data generated that is useless.
See Why do I need to do calibration myself? for information on why vendor-supplied profiles are often worse than useless."
