Anywhere from a few months to years. RGB is a bit of a issue; while they could use a variant quality of LED's to account for the efficiency loss, the issue would be the higher the quality=the greater the luminance/intensity.
So putting a red, green, and blue LED's of varying qualities together will produce a tinted backlighting.
The RGB Solution:
PWM+Controllers. They could utilize PWN's and sophisticated controllers to control each color LED to match luminance/intensity of the other color LED's. The PWM/Controllers: would have to be done in segments of around every 2-4 square inches, because controlling the whole panel with one PWM controller would be impossible since PWM controller doesn't allow for multiple channels of voltage tweaking.. Also a secondary control would need to be used to tell the PWM controller what to do, depending the colors displayed.
Wait for LED technology to better life expectancy across the board on RGB colors enough so that it won't be noticeable for many many years.. Something tells me this leap in technology shouldn't take much longer.

Hmm.. Not sure what to say.. CCFL's do a very good job already.
But no there isn't I suppose.
