This "8-bit" colour is not the same as 8-bit colour depth on, say, you PC. This "8-bit" or "10-bit" is in reference to the sampling size of the analog waveform of each component of the video signal.
Increasing the sample size beyond that of the source material is only - potentially - going to give you a marginal improvement, mostly in fine gradients. I certainly wouldn't choose my TV over this as there are many more important factors to image quality and accuracy.
