Yes, that looks just like one of the tools provided by graphics card
vendors to adjust the output signal of the graphics card.
If it is what it looks like, it essentially tampers with a look-up table
in the graphics card that maps framebuffer values to more precise values
sent to either the LCD via DVI connector or the DAC generating the VGA
signal.
My Nvidia graphics card also came with a tool that would help you set up
that curve properly.
