I don't think this lut is for a particular monitor color space because 
we use it only for a certain project. Actually, some shots within the 
projects don't use any LUT and we look at our renders with 2.2 gamma in 

It is a 3D LUT provided by the client used to visualize their plates 
that behaves similar to the second case you described. They advised me 
to make a color correction in Nuke per channel on the HDRI to make 
things look right when I light.

In fact yesterday somebody told me Houdini doesn't allow 3D LUT so what 
we're looking in mPlay is not even right.
