Thats a great question.  The answer is yes, but do you really need the added objective size?  Alot is said, especially on this forum about large objectives and the need for having one to be able to shoot into the night.  Personally, most shooters can get by with a smaller objective, that has a lower profile and provides a more comfortable shooting position for those 99% of the times when it will be used, i.e., useful light.  Alot has been written by the major magazine writers like Craig Boddington, Layne Simpson and Jon Sundra and most of them prefer smaller objectives.  Now, if you are really going to do hunting in really low light or at night, its all a different story.  I would say most of my scopes are 40 or 42 mms, with a few 50 mms and one 56mm.  I personally like the aesthetics of a rifle and to see a beautiful light mountain rifle, like a Tikka T3 with a monster 56mm scope on top, that not only ruins the balance, the idea of a nice mountain rifle, but makes it look horribly awkward.

Not enough to make a difference!!! The larger objective scopes are more costly, a little heavier, their higher profile doesn`t look as good and there is no advantage in owning one under any light condition!.........A 40mm, a 42mm vs. the 50mm and 56mm`s, will not make any difference whether your hunts are successful or not!! If it does? Then the problem is you!!!

If there is a difference?? Any difference will not make the difference between success or failure!

I am going to have to pipe up as the argumentative one in this case. (well partially anyway) For me the issue is one of exit pupil. In low light, I prefer the exit pupil to be around 8mm. That means that I don't like to go higher than 7 power with a 42mm objective. All that said, it isn't practical to use a 80mm objective for a 10 power scope.

So, in practice I prefer to limit myself to 6x42 or 10x56 in lower light. This is part of my preference for moderate powered scopes. With variable power scopes it doesn't make that much difference as exit pupil changes with power.
