If you live near grass & trees, do the ones on your TV look like the ones outdoors? Does the sky have the same cast??
At night, in low or no room light, does the light coming off your screen resemble that coming off your local cinema screen? And how naturally crisp are the edges of subjects? Does everyone look like they are wearing eyeshadow?
I leave it to your good judgement to provide answers to these questions in light of even a basic calibration with Digital Video Essentials, AVIA, or Getgray.
