No. Data is data, packets are packets. Streaming *can* but not because
it is streamed, simply because the codec requirements for the
streaming platform are different, so the data you are delivering is
Of course chosen datarate of the encoding matters hugely for overall
quality, only tangentially for color.

Yes, but no different than any other platform in that you make
different decisions for encoding based on content.

Sure, given the state of devices, the market, and likely viewing
Color issues are not at the top of the list, bandwidth is (any ATT
customers here? yeah, me too, sorry). It is my understanding that the
iPad displays use the same LG panel (different size obviously) as in
the newest CineTals, though with a completely different method of
backlighting. Would be hilarious to do a spectro profile of an iPad.
Color fidelity is dependent entirely on the display device and the
sophistication of the underlying platform, and I'd argue that the only
mobile devices relevant to video are the iPhone, iPad (yeah, ok semi-
mobile) and the Android phones with big screens.
Those are all LCD, smaller versions of your normal LCD displays with
various backlighting techniques. Long as you're encoding black
properly (that is, your video data is good) then the display on those
devices is more than acceptable, it's actually good.
