You can view the TV as a computer monitor if you want, but then you have to view every possible video source as another computer feeding another signal into it that may or may not be anything like the signal coming out of another device. Switch from a DVD player to a DirecTV box, and you'll notice some differences in the picture.
So now every device would have to have its own profile, and it would have to be capable of sending said profile to the TV in some way that couldn't be usurped by changing inputs on the TV itself, otherwise you'd have mismatches happening right and left. Since you probably wouldn't want to send that much data along with every single frame, that means a new transfer protocol, a new cable, and new hardware. That means prices go up on everything.
Then consider the fact that 99% of all users don't want an accurate display, they just want TV to look good to them. That generally means high contrast and high saturation, and if they aren't getting it from a certain source, they want to be able to dial it in quickly right from an onscreen menu or button, not setup some elaborate diagnostic rig and spend two hours fiddling with different settings until they get the result they want.
There may be a limited minority of people out there who, after dropping $5,000 on a TV set that's going to die and need to be recharged repeatedly, would have no problem purchasing another $5,000 worth of calibration equipment and software to profile every possible video source at their immediate disposal, but certainly not enough to justify the engineering expense at this point in time. HD itself is still a hard sell for most people given the limited amount of HD programming available.
