Even in the context of something normie-friendly like Skyrim, TES lore is way too complicated to condense into a television format. The most unique part of the series' lore/writing is that you can't trust anything you read and most historical events are told by unreliable narrators with heavy biases.
If you had to turn it into something TV-friendly it could be an anthology series where each season covers some major historical events but from the perspective of the different races.
