Technical question on font rendering (gamma correction)

Since Qt 5.9 .otf fonts have been rendered with alpha-blending and gamma corrected in Qt apps / environments. The only other rendering engine to do this is Skia (used in Chrome browser etc.).
I have a hardware calibrator device for my monitor.
My question is two-part:
1) What real monitor gamma value does KDE assume to do the gamma correction? 2.2?
2) I have noticed that a slightly darker gamma on my monitor is preferable, as the desktop looks slightly washed out at the default. Is it better to:
a) calibrate my monitor to 2.4 instead of 2.2
b) calibrate my monitor to 2.2, and use the KDE software slider in system settings to reduce gamma from 1.0 to 0.9?
