DVI output of a cheap DVD player always same ??

As you probably all know there is the Bravo DVD player, which is the cheapest DVD player with DVI output, and you have a Denon tope model DVD player (very expensive) also with a DVI player.

If you connect this cheap & expensive player with a decent video projector with a DVI cable connected would you see the difference or not ??
As DVI does not make any conversions, and is as pure as the original signal, or am I wrong ??
