Affect all channels and elements

[R2J2]

when using affect all channels option I'm having trouble comping the elements back
elements are like the diffuse in my example, having the refraction show through
using minus almost gets there but with funky negative values and the reflection element gets nowhere close

I would like to have 2 options in my comps:
*comp back to normal but with matte elements etc using all channel option
*comp it so that you can grade say the lighting and have those changes pass through the refraction (I did get close to this)

so nothing on this?

It might be hard to get it to work; for example, you have no way of telling which part of a reflection element comes from the glass, and which part - from the obejct behind it.
