The LMT should be applied on both the footage and renders, after
compositing. If we apply it before they wouldn't be both in the same
linear space.

>From looking at the ACES test images, and feedback from Jeremy Selan,
this increased contrast is just the default look we get from ACES,
there's nothing wrong with it, it's just the starting point that we
then tweak further. Also note this increased contrast is visible when
applying the ACES RRT to rendered images, it's not a feature of the
footage.

So I don't think we're missing a LMT from the DP, it is simply a
creative decision that will need to be made by the artists here. As I
understand it, for Mango the role of DP is more limited than perhaps
is usual, grading / color decisions will be made by the artists here.
