I see.

In fact, we made the complete profile with the first config (measuring
reflected light on the screen). Then, we made a simple calibration with
the second config (towards the projector, with diffusor on): loading the
new lut values did not change much the results. Especially, we didn't
notice a color cast. So, I presume it is a not so bad config (again, it
will be the only one we will able to achieve for the large projection
room).
