For you chemistry and physics types: does the lifting power of helium change according to how small of a space you put it in?

Say you have two balloons. One will hold 1l of helium at STP. The other will hold ½l at STP. You fill the balloons with the same mass of gas.
Is there any difference in the amount of lift generated?
For the purposes of the exercise, the balloons weigh nothing on their own, and will not break.
