Absolutely, nobody writes music for a true orchestra. NEPV follows the grammar of a live, un-amplified orchestral music - when soft instruments are played alone without the sound of other instruments overwhelming it. In other words, you can take the songs and play live acoustically (without amplification) and it will come out fine (no need of mixing instruments at different volume levels).
BTW, watching the audience react to the orchestra- I think IR needs to give an intro to how to listen to a real concert. Just listening to the main tune is not enough. That is a trivial use case of an orchestra. You need to listen to the parts being played all the instrumentalists. Some of them are true counter melodies which sometimes can stand by themselves.
Its a pity in that noise the audience missed out on so much of the music being played. I guess, it still happens to all his film songs - appreciation for the tune, but no appreciation for the harmony,basslines, interludes etc.
