I would like to know how you can for certain say this...
All Film Cameras/Digital Video Cameras/Digital devices such as computers internally are gamma 2.2
All video games are gamma 2.2
All Digital Movies like Toy Story are gamma 2.2
I am not going to set my display to anything other then 2.2 for a small number of movie studios that don't follow the real standards during post production.
A set of gamma curves represent how the image data in an RGB image file translate
into measured screen brightness for each color. Commonly, an ideal gamma curve
is represented as an exponential relationship which approximates the response of
the human visual system. In this case, the gamma curve is described by a single
number which is the exponent value. In Microsoft Windows, a standard gamma of
2.22 is the most commonly used value, and this is also the standard used for the
web, video, most monitors, and Photo CD. The prepress standard is gamma 1.8
which approximates the characteristics of a printing press.http://ftp2.bmtmicro.com/dlc/Color%20Management.pdf
