RGB Gamut Levels Broadcast

If it helps - I've attached the i-comply preset settings that pass the test file I've been using.

It's in IRE as a scale, which tricks me a bit as I generally work in millivolt or bit values. Anyway given that you said that it also still fails the gamut test, I think it's doing exactly what Limiter() is doing. Also, the reason why you don't notice a change is that iComply is clipping (i.e it's cutting off values that are outside the limited TV range) while if you use tweak() it performs a rollback in which values are shifted backwards (and therefore preserved) but of course it will affect the final result 'cause everything is desaturated.

Honestly speaking, though, do you really need to do that?
In like 90% of the cases, just Limiter() is enough to pass QC and you won't notice a shift as it will do exactly what iComply does.
