someone please give me a display that shows the colors that CAN be seen by paper....and are seen exactly the way they are seen by paper.....
Photoshop's soft proof is supposed to do this (sort of, kind of) using the "Make my image look like crap" button (Simulate Paper/ink). Schewe covers this well in the tutorials you can get here.
The big issue is handling dynamic range which is vastly different on paper versus the display. But an emissive display and a reflective print will never match exactly just as a chrome and anything you print (despite the gamut of an ink set) will never match exactly. We hope to get as high into the 90% range as the law of physics allow.
But your point is well taken in terms of getting as close a match as possible. There are some things that hopefully future technology will allow Photoshop (or maybe LR) to do better.
i use to work in adobe prophotoRGB....until i found out that some of the best retouchers work in Colormatch RGB....closer to paper and still shows much more then any magazine print (that goes for ads as well....)
That's a bit like throwing the baby out with the bath water. First of all, the main advantage of ColorMatch RGB is its tone response curve of 1.8 for output to press conditions (this TRC was set this way to account for dot gain). Its a space designed many years ago and for prepress work. That's probably why so many of these retouchers are using it (or its just out of old habit). But the gamut is pretty small by todays standards, not much bigger than sRGB. If all your work goes to press, OK. But enter a K3, let alone HDR ink set, you're tossing a lot of printable colors.
These newer wide gamut displays are useful to some degree in that they now allow you to view colors broader than sRGB you may have in your wider gamut working space that you can print. The dynamic range issues, the ability for better soft proofing simulations etc are all different issues and a wider gamut display isn't necessarily worse for you in terms of getting a good/better screen to print match.
Your initial reaction to "Colors as they cannot be seen on paper" however is a good one. I'm not sure what that is supposed to imply that's useful in the context of photography for anything other than viewing images on this particular display.
