Color Shift when exporting ProRes in AE v 23.1 on Mac

I am sure you are well aware of the following problem, but I could not find a solution online and it does not seem to be fixed? 
When working with Arri Alexa Mini LF footage (ProRes/.mxf) there is a color shift when exporting in ProRes 4444 (trillions). 
I used the official sample footage from Arri: https://webgate.io/directlink/b043cddb9c4658e0 

Clip: F003C003_190925_MN99.mxf 
I tried everything, different software versions, hardware accelerated decoding on/off, different computers, depth, premultiplied/straight... 
There seems to be a slightly different problem with Premiere as well. I think it might be a problem with how the file is interpreted by AE because it seems to help to re-encode in ProRes 4444 with DaVinci first. 
Also AE shows the file as millions of colors (if I understood correctly that means 8bit) what would be wrong in that case. 
The Arri Alexa series might be the most important cameras right now and it would be really important to have a flawless workflow for these files/codecs. I'd highly appreciate any help that I can get for this problem, maybe some of you guys can try it yourself? 
I added stills with the shift to my post. It seems really subtle, but when grading that can be a huge problem.

    Thanks for posting here! 
    I just tested it with AE 24.6.2 and it seems to work now. I remember talking to support for hours and hours and nobody actually listening or acknowledging that there was a problem. I really hope they invest in solid color management from now on because the trust of the community was lost for sure. 

    Best,

    That color shift was so annoying, it was almost impossible to work. Could not trust any render from AE. Impossible work with camera files. Everytime i was asking exports log from DaVinci. And only then could work with those files. But if i correct understand they fixet it now. Can you also confirm that now everything is correct? became paranoid.
