How to ensure that the formula color == (diffuse_reflectance * diffuse_illumination) + residual still holds after the data undergoes tonemapping?

After tonemapping the color image, the relevant equation will be:

tonemap(color) == tonemap((diffuse_reflectance * diffuse_illumination) + residual)

But in general you can't simplify the right-hand side any more than this.
