No, they are not that different. The Dwarves of Erebor are quite literally Dwarves of the Iron Hills who have returned to their old kingdom (because the Iron Hills Dwarves were originally refugees from Erebor). The two groups most likely share Daín II as their monarch, and have no cultural or visual differences. There need be no distinction, except their speech banks.
