There is a flip side to this too though. They're also playing the better teams more as well. Those teams are better than Cleveland and Chicago. Both cases are true for those two teams as well, however.
I don't think the schedule is a huge difference, but I do think it can have the potential of maybe 5 wins. In the grand scheme of things, that probably isn't a big deal since that also applies to the other division foes as well, but it probably matters when it comes time for playoff matchups.
