The section on display_gamma points to 6.11.3 for more information on gamma.
6.11.3 Assumed_Gamma
---
no assumed_gamma in scene :
No gamma correction is applied to output file.
assumed_gamma 1 :
Gamma Display_Gamma is applied to output file.
If Display_Gamma is not specified, 2.2 is used.
assumed_gamma G :
Gamma Display_Gamma/G is applied to output file.
If Display_Gamma is not specified, 2.2/G is used.
Recommended value for assumed_gamma is 1.

The render window displays the image as it is written to file.
Radiosity works best with assumed_gamma 1 as will any feature
designed to simulate reality, like fresnel reflection.
Two tips to ease your path to enlightenment:
Write rgb 0.2 instead of rgb 0.5 and rgb 0.03 instead of rgb 0.2.
Don't hesitate to use image editor to enhance contrast at first.
Oh, and rgb 0.8 -> rgb 0.6 :)
