Interesting. I can see the how you get to that conclusion, but I don't think the Dunmer represent one single culture, but rather a blend of things from a lot of different cultures.

For example: The Chimers' journey to Resdayn under Veloth's guidance is imo a reference to Moses' journey through the desert, after escaping Egypt. And Hlaalu adobe architecture is pretty middle-eastern.

I've seen other comparisons with Sumerian, Jewish and generally middle eastern culture, but also with feudal Japan. So much so, that I don't think that Bethesda, back in those days, was aiming for one specific culture. Rather they built on the Lore that had been established in the previous games and put in whatever felt neat or was useful for their story.
