Looking into the history of this ticket - it was marked done April 2020. There’s a note saying that the work improved the color fidelity vs what it was prior.
However, it does not overcome the underlying issue: the brightness value of some frames will cause the red hue to shift pink. I’m not sure it can be fixed without revamping the artwork on some frames, and doing that comes with risks.
I know there’s a lot you wanting a redder red. Let me ask: is it worth the risk of introducing new problems? If it is - I’ll advocate for this to be revisited.
