For *best* color calibration, you need a spectroradiometer. Much less expensive would be a colorimeter. Of course, some software (which might be included) to throw up the test colors to be calibrated.
A pro calibrator would use one of the above. At least if they weren't ripping you off. They'd do some tweaking in the SM. Some devices, even of the audio kind (read Anthem), offer gamma curve adjustments, if very expensive.
What most of us do otherwise is use an affordable test disc with tints that we look through. Something like Avia II or DVE. It ain't the best, but it's a lot cheaper.
You might be familiar with some numbers, that don't have much to do with your questions regarding color, but just in case, I did find this for you after a brief search:

*The issue with trusting someone else for your display is that there is unit to unit variation. The amount of variation with a product is not necessarily representative of its value or quality, but it could be. For instance, Pioneer Elites have an extremely small variation, and of course are well reputed. OTOH, some items like previous Epson projectors are also known as fine values and good performers, but would suffer from quite exaggerated OTB variation. I don't know about Toshiba LCDs.
Of course, the amount of light in your room, the color of your walls, do make a difference as well.
