Problem summary
Some colours in some OCIO Configs are transformed incorrectly by the Canvas' View Transform.
This is noticed when picking a color with the Color Picker's View Transform set to the same Colorspace as the Canvas' View Transform: The picked colour doesn't match the Canvas' colour.
Customer reported platform
CentOS 7
Steps to reproduce
Launch Mari and open any Project, such as the Example Project.
Confirm that the View Transform Colorspace in the Canvas Toolbar is set to sRGB - Display:
Open the Colors palette and set the Color Picker's View Transform Colorspace to sRGB - Display:
Create Paint node that is also using sRGB - Display as its Colorspace, and set the color to, for example, pure green:
View the Paint node and, using the Eye Dropper tool, pick the green color in the Object.
Expected behaviour
The green in the View should match the Green in the Colors palette.
Actual behaviour
The green in the View is darker than it should be:
