Bug Description
$ xrandr --output VGA1 --gamma 1:1:1.7
$ xrandr --verbose | grep -iE '(gamma|bright)'
Gamma: 1.0:1.0:1.7
Brightness: 1.0
Gamma: 1.0:1.0:0.59
Brightness: 1.0
$ xrandr --output VGA1 --gamma 1:1:.6
$ xrandr --verbose | grep -iE '(gamma|bright)'
Gamma: 1.0:1.0:1.7
Brightness: 1.0
Gamma: 1.0:1.0:1.7
Brightness: 1.0
As you can see in output of commands above, "Gamma" values printed by xrandr --verbose are exactly the invert of the values set: 1/<value set>... Appart for value 1.0 which is correct.
