I reviewed for myself how LCD monitors work.   Is there anything, such
as the brightness of the light soure, which one adjusts at the hardware

Typically the brightness (backlight intensity) is a hardware
adjustment that doesn't compromise the image quality. More
advanced displays that use RGB LED backlight will allow
white point setting as well. If the display has greater
than 8 bit precision internally, but the graphics card
LUT or interconnect (ie. DVI etc.) is only 8 bit and
the calibration package can't set the internal LUTs (ie.
Argyll currently), then there may be advantage in setting
transfer curve (gamma etc.) on the display as well.
