Luminance Calculations using Iray for 3ds Max

Avid user of Iray for 3ds max as a tool for lighting design at work and in school.
Why is there not an option to produce false color images with luminance calculations?
It’s possible to get illuminance calculations. Seems like Luminance calculations should be possible but there is no option for it.
Is this being developed?
