You could not be more wrong about this. Any professional will tell you that the glossy screens do not reproduce colours accurately at all. Anybody doing serious photo/video editing uses matte displays.
The glossy displays seen on MBP's and cinema displays look beautiful, I agree. But that is because the blacks are crushed and colours are overly-vibrant.
If you don't believe me, try and buy a professional IPS panel monitor specifically designed for photo editing with a glossy display. You can't.
Because no one uses them.
