See the type just above? It's from my system profile on my 27 inch Apple iMac. Look down to the
third line. It shows the pixel depth for the monitor to be 32-bit. This is one of the changes that Apple's new system software (10.11.1), El Capitan, delivers. That might mean that we're now getting 10 bit per channel color! I love the idea of it but have no idea yet whether the increased bit depth is only available in Apple programs like Photo and Preview and not PhotoShop, etc., but I'll wait to hear from our more technical and enlightened readers before I stumble into meaningless conjecture and outright Male Answer Syndrome.
