The one issue I seem to see here is that the Dp used the true light system here to establish a look.
If you by-pass his look with a plug in from someone else you are going to be compromising a look that they might have been going for. It sounds like a communication gap. The Dp was probably under the impression the luts would be recalled and used in the edit. Or maybe he thought there would be a grading session.
Interesting situation indeed.
I just finished shooting a pilot for NBC with the Alexa. I established a look in ny on a bones system but have to grade in la on a davinci. So I will have to have the ny post house send over my dailies lut files from there system that can be read on the la system. Just to have a base to work with. But I also confirmed that I would have a grading session before we started shooting. So I am covered either way and so are the post
I think workflow communication is essential in most digital productions these days.
