Can Pitch/yaw/roll have less than full inputs with joystick?

[Nightside]

Playing with a controller- is it possible to have less than full input on an axis? 

For example: Pressing up very slightly on joystick gives full input(visible on the little gauge at bottom left), even with caps lock on. I tried reducing axis sensitivity to 0.05, but it made no difference.
On keyboard this on/off behavior makes sense but it seems like joystick should allow more subtle control.
