If there was another international route out of Denver, I think it goes to somewhere else (CDG would be my guess).
Norwegian currently flies DEN-CDG (seasonally), I don't think the market would support two daily non-stops.
With AMS, I did read it is the top international destination out of DEN without non-stop service, there is a lot of tech and finance in AMS that could support business travel, where CDG would be more leisure.
