BUG: Prores false colors in AE CC 2020 (except up to 17.0.2) (!)
Recently i found that export in Prores 4444 or 422 in AE render queue is changing colors in final output even with different color depth. In millions of colors its slightly redish, even hard to see, in trillions - more wrong! (pic .1)
AE 2020 (except up to 17.0.2) detecting wrong color depth (pic. 2)

You can render out two files in render queue and compare them in composition.
Working space - none. 32bit depth.
AE 2019 Prores - fine. ME 2020 Prores - fine.

I am also seeing this same issue. It is a very small shift that you will only notice with some content like this. A PNG sequence export looks fine and matches the original comp.
Additionally, every 2018 After Codecs export has the wrong color interpretation in 2020. Those 2018 After Codecs version of ProRes match the Raw when re-imported to 2018, brought into Nuke, and Davinci. ProRes XQ has a similar problem where the green is over-saturated in 2020 (looks fine in Davinci, Nuke, and Adobe 2018).
