Probably, I dont know about 40,000 to 80,000:1. Since the way our eyes interpret light is not linear, it is hard to say without me testing it. Never had a projector that can go that high. I do have a 1,500:1 projector here and a 35,000:1 projector here, and I can say that it's huge at that point
I remember the Epson 5010, this is what 5000:1 native on/off, and 18,000:1 to 25,000:1 dynamic (depending on who's measurements you believe), I think still a nice bit of difference between the Epson and JVC but certainly not tremendous compared to 1,500:1 to 35,000:1.
