LWF problem with IES light

[vizuals]

Hello

I made this scene of a bathroom, with spots in the ceiling
The spots are point-web-IES
(NON-LWF .... colormapping exponential bright 3.0 and dark 3.0)

They cast nice light on the walls.



Then I thought I'd change to LWF (liniar workflow)
And rendered the scene without colormapping, and I totally lost the nice lightcast on the walls.



Can anyone tell me why this happens, I have tried to get it back, without any result.

It has to recast the intensities - all your multipliers should be effected.
