Calibrating multiple inputs was more essential with analog video, where the actual signal quality could vary from device to device, causing different responses in the display. With HDMI devices, issues where the data coming is different than another device would be due to the device having something wrong in the design, and those often aren't errors you could calibrate around. Exceptions to this would be if you are running a device like the PS3 full range for games and running other devices, like a TV/Satellite box and Blu-ray player, in standard video range. But typically, if you get it right with HDMI, it should be right for everything, otherwise it's the source that is at fault.
