The First Dominion in ESO wasn't as nearly bad as the Third in Skyrim. Very condescending and low-key racist towards humans, but put the Altmer, Khajiit, and Bosmer on equal footing. Then things changed.

I suspect that sometime after ESO, the Veiled Heritance (a group of Altmer supremascists) took over. We see them try to infiltrate the Thalmor in ESO, and I suspect they succeed after the events of the game, which would explain why they go from "maintain order in the Dominion" in ESO to "Elf Nazis who oppress any non-Altmer" in Skyrim.
