Good god yes, all too familiar. I'm sure all the seasoned pros will have responded with sound advice by now, but I have come against this soooo many times.

Found different solutions for different projects but each time it seems to take something different. One solution I remember was rendering/encoding with a gamma adjustment of +12 (in Episode) which felt like a brute force workaround rather than a cure of the root problem, but it got me where I needed to be on that day.

Good luck, I look forward to all the other answers too
