InfiltratorDemo is too bright and colors are washed out using OpenGL4 on Linux

There are instances in the showcase where the brightness and colors look normal, but most of the time they are off drastically.

I cannot reproduce this with SM5 on Windows, nor can I with OpenGL4 on Windows.

Repro:

1. Create an InfiltratorDemo project from the launcher.
2. Package InfiltratorDemo for Linux and transfer it to a Linux machine.
3. Give the package permission to execute and run it.

Result:
The stealthy demo looks like it is being run with all the lights on, the colors are washed out to the point that black looks like light grey, and the view outside looks like it's daytime instead of dusk/night.
