Yes, Philippe (Faucon2001 here on AF) had done a lot of testing on various NVDI drivers on printers couple of year back.
IIRC, he did mention that the deskjet drivers can never get the good colour reproduction on colour laser because the of the driver optimise the way the ink is sprayed on the paper... my guess is it takes in to account the way ink spread over paper and model of device as well. Whereas toner does not need this and just coat the entire paper and let the laser/led fuse it into the paper.
But in general, you can use the NVDI PCL driver for any PCL aware printer as they are still backward compatible (read as almost all modern printers).
I have still to see PCL6 only devices in home consumer models market..... but I am no printer expert may be they are slowly coming.
Guess you can search for Philippe's findings here (at least I think it is documented somewhere on this site.).
