Whenever you do that you will introduce more artifacts when you expand the file back to a normal contrast range. Also looking at the parade of an ungraded clip is relevant and important because it shows you how much compression is being used.
In the older generation file note that the highlights are actually continuing beyond the 1023 mark and in fact can be pulled down. In essence that "film" profile uses around 90%or more of the available luma range when writing the file to ProRes. The new 7.3.2 uses approximately 64% of the available luma range and that means it must be expanded much more extensively to get to a normal/pleasing luma range. When you do that you will make the noise in your file more apparent and much harder to manage. You might also introduce banding in some sky areas etc...
I feel like there might be users like me who might benefit from knowing this. I am just trying to put information out that might be relevant to some users.
I understand your point, but I would like to know more about your grading workflow.
Do you grade prores manually? Cts? LUT? What color space?
New gen5 is very different about contrast curve, but also be cause curve is the same for all iso, in past was different, and if you delog in a wrong way, may be that you cause more noise enhancement than you want.
I understand that prores is not 12bit raw, but is a 10bit file, to create banding on sky mean that could be something of wrong in delog workflow.
Anyway is better (if you need more cleaner picture) to go in 1250 which is second gain, more cleaner than 1000 and eventually go down in post.
