You are right and wrong in my opinion. Yes, the colors are different, but in my opinion that’s not because of the cam, but because of your mac screen. Those screens are always way to yellow.
I use the cinema display (the older beautiful not shiny ones) and use this for coloring (not for broadcast, only web). I know this screen, it’s always more yellow.
I find the picture of my ex1r very ‘correct’ to what i see in the finished production. (i always put in a lot more black though).
