Will the addition of a yellow filter on a TV really add that much to the color quality of the picture?

(My terminology may be way off.)

Sharp is introducing a new TV that adds yellow to the typical RGB color filters. Supposedly, this combination enables more than one trillion colors to be perceived by the naked human eye.

Will this new technology really make that much of a difference in what I see on my TV, or is this just a marketing ploy? I am in the market for a new TV and I am wondering if I should wait for this fshmancy new one.
