Are professional cameras accurate of real life?

For example canon cameras. Do they video people just how they look like in real life? Also, are they better than iphone cameras, if so, why?

Are you seriously asking if a professional camera is better than a phone for taking photos or video?
Really?

If they were the same, or even nearly the same, why on earth would anybody be crazy enough to spend thousands upon thousands of dollars, plus basically break their backs everytime they have to carry it around, when a little TELEPHONE gives the same results?

Can you really not imagine that perhaps - just perhaps - there might be a bit of difference thanks to optics, sensor sizes, features, etc?
Really?
