Re: DCP AUDIO LEVEL

As I suspected. Did you make a note what type of processor they use? Because, 85dB is common only at 7 - below 7, the various cinemaprocessors use different attentuation curves. Depending on the type of processor, 5 could mean between -7dB (Dolby) and -10dB (Datasat/USL)
So, did they say that their normal feature level is 5? Some people would say - '7 is the standard, so it should be right!'
But, as matter of fact, no cinema plays features at 7.
One problem is - your peak level in Ls and Rs is already quite high - look at the end of the chorale part.
As I wrote above - you may need to reduce Ls and Rs by e.g. 6dB in order to gain enough headroom for a global gain adjustment. Otherwise, you may only increase overall volume by around 5dB before you run into clipping in Ls and Rs. I think +5dB global gain is not enough. That based on the assumption that the chorale passage has the highest peak levels in the whole piece. Can you show us a screenshot of the audio analysis for the whole piece?
