Camera image contrast, vividness

The images provided by the simulator are a bit shallow, lack contrast (see images below). This prevents color validation in the case of our AS. To confirm this issue, I messed around with rgb values in our code and it does seem to affect how successful the validation is. Giving it a bigger threshold in color values seems to help but it does not work as intended.
Real world data: (camera calibration is a bit off, but that's beside the point)
