That is not enough of a change to be worthwhile, and if it won't stay in the highest overdrive gear on 3.73, it likely won't with a 4.10. With a six-speed automatic, you have a selection of overdrives, the automatic will figure out which one is needed for the load and speed at any given time.
Most of the time when manufacturers go for steeper final drive, it is to raise the GCWR, get the overall gearing low enough to meet the standards for starting from dead stop on a grade, taking the hit on MPG at highway speed unloaded.
