Unless your viewing software does actively compensate for your CRT's 
gamma, then it /is/ an issue with your display: By default, both the 
interwebs and your operating system (presuming it's Windows) will assume 
a display gamma of around 2.2.

To view the image correctly:

- Set up an orthographic scene in POV-Ray to just render an input image.

- Set #version to 3.7, and assumed_gamma to 1.0.

- Render with option Display_Gamma=2.5

What you /then/ will see on your display will be (approximately) how 
other people see that input image.
