How many of the DoPs are also the editors/colorists? They might not see the benefits because they arne't seeing the image benefits in post workflow. Image quality is not the soul factor of camera choice. Ergonomics and workflow also play big factors. Yes, RAW gives you more options in post, but with this camera it takes a lot more to get, and for some it's not worth the aditional effort.
Out of curiosity, why are you worried about what other DoPs are doing? The most important opinion to you should be your own.
