PZ85 and Color mode: is it 8 or 10 bit?

Hi all.
My question is more or less the one in subject...
I actually don't know if that has been already discussed on other posts but...

I've checked up and down the specs on the Viera brochure and i can't make up my mind about this feature since in certain point of the file it's written "deep colors", other it's only mentioned "8bit color".

And more, where 8 bit colors were confirmed, is it a main issue that should stop me till the PZ800 or just a minor one?

Thanks in advance for your time and replies.

Cya.
