i’ve never had any luck with animation codec. Try other professional codec like Prores or DNXhd. you might have to download the codec pack

Anyways use I would suggest use Prores HQ or DHXHD 38 bit. there under codec setting you’lll have option to select RGB values.
Also these codecs will help you preserve the quality when changing between applications. Usually when REC 709 is selected the output is washed out because it takes the highlight and shadow clipping into account.
Also try to export h.264 format. see if that matches.
thank you
