Should make NO difference if you're viewing the files in an ICC aware
application. The display calibration target values and the output are
separate here. It's possible the output profile preview tables are funky or
something else is going on. With the same output file, calibrating to 1.8
versus 2.2 in something like Photoshop should show no difference. The
Display Using Monitor Compensation in Photoshop adjusts the display preview
for both target values.

Outside an ICC aware application, that's a different story. 1.8 would most
certainly produce a different appearance from the same file compared to 2.2.
If you're calibrating and profiling your display, this is a moot point; the
preview isn't color managed.

That says a lot!
