I think you are probably right. I think load capacity is only related to the amount of air in the tire, and when you don't increase the physical size of the tire, you can only get more air if you can increase the pressure. And you only want to do that if you have more plies on your tire that can withstand that pressure.
Tirerack seems to say the same thing. They say:
"All tires with equivalent physical dimensions carry equivalent loads (until they reach their maximum load pressure)."

But in the case of an LRE vs. LRD tire, for example, while their load capacities may be the same at, say 65 psi, I would think the LRE tire would be able to better withstand aggrevating factors like heat and bumps. Or maybe that's wishful thinking. But I can't seem to recall anyone have an LRE tire blowout here.....
