In Render properties > Color Management > Display.
* Off: Directly output image as produced by OpenColorIO. This is not correct
in general, but may be used when the system configuration and actual display
device is known to match the chosen display.
* Automatic: Display images consistent with most other applications, to preview
images and video for export. A best effort is made to emulate the chosen
display on the actual display device.
The option is grayed out when the current OpenColorIO config and display/view
does not support emulation.
