Equalize RGB in Renderer element

A small question about the “Equalize RGB” option in the Renderer element. We’d like to equalize across two different renderers. If we select them both we have the option to check the box to equalize, but if we return this option is unchecked. Can the equalizing be done across more than 1 renderer? We’d also quite like to know how this function works (will this equalize stimulus luminance etc).

Equalize RGB estimates average RGB luminance across loaded picture items in Renderer. Then, all pictures normalized to that mean such that the pictures have the same RGB luminance when shown. The RGB luminance of a pixel is estimated as a simple mean across R,G,B channels and the alpha channel is ignored.

Unfortunately, it’s impossible equalize luminance across different Renderers (e.g. it can be very slow).
