Could be, but having more discriminating data as an input can only improve speed and accuracy. I don't know what technology they picked for the first iteration, but can only imagine they'll end up using every trick in the book going forward. A slightly more advanced sensor or lighting apparatus wouldn't cost much more, proportionately to the cost of the whole system.
