PS:

Apparently the NVIDIA driver for Windows supports this as well, see following
screenshot and forum thread for example:

http://abload.de/img/hdmi-content-typebtumj.png
https://forums.geforce.com/default/topic/814785/hdmi-content-type-api-/

Also found something on hdmi.org:

https://www.hdmi.org/manufacturer/hdmi_1_4/content_type.aspx

Apparently there is not just a setting for "IT Content", but for "gaming,
movie, photograph, and text viewing modes".

And the receiving display can alter it's processing settings based on which
type of content it receives.

It would be amazing if that would be possible on Linux as well.

Looks like other Linux users have complained about the lack of such an option
as well:
