is digital vibrance option available in XPS 15 ( L502x )?

hi,

I have a Dell XPS 15 ( L50X ) with Nvidia 525M 1 GB graphic card. I was reading an article on nvidia website regarding the Nvidia Control Panel, and I saw that they mentioned Digital VIbrance feature, which enhances the color to some extent. I checked on my system nvidia control panel, but that option was not there. 

Has this option been removed or is it not showing up only in my system? I have installed latest Nvidia Driver 185.62.

Thanks 

Ravi
