Yes it's going to be handled. There's an exposure parameter already, that can be used to boost the light levels, emulating the adaptive sensitivity of the human eye. The exposure is being already adjusted during the day to compensate for changing light levels, but at night it's clamped to some value. Actually it's not pitch black, the ambient light level at night is quite visible for me (it depends on your monitor settings). We can make it adjustable though.
What's missing is the loss of chromatic perception at low light levels. When the light goes down, the colors will slowly fade to grey shades.
