There are just some special to macOS only things that may require adjustments. mp4 container was developed by Apple, NCLC tags system (currently extended and used in h264/h265 specification) also was introduced by Apple in Quicktime container long time ago (but was ignored before wide gamut HDR and wide gamut displays start move to masses).
It sounds strange and insane but there are two places to put tags in video. One group of tags located in codec stream itself, and another located in container.
Currently ProRes in FFmpeg/Hybrid place tags only to one place. As result tags are visible in media inspectors but ignored by native quicktime-based players color management. I found this problem yesterday and not sure yet where to report it
Not a critical, because i can add missing tags, aspect ration and other missing metadata with JESExtensifier or with AMCDXVideoPatcher instead http://mogurenko.com/ but improvements are always welcome.
Apps like Davinci Resolve write proper tags in both codec and mp4/mov container.
