Okay so I recently watched some videos of "The Elder Scrolls Online" the other day and got hyped when I finally noticed they did something awesome with the daedra!
That thing being they confirmed that some daedra, who can have different owners, will actually LOOK different base on the owner!
For example, in the main series... We've seen daedra pretty much from the Oblivion Wastelands (Mehrunes Dagon's realm). Thusly we got generic orange flamed atronaches, demonic dremoras, etc...
But in The Elder Scrolls Online, most of the daedra are coming from Coldharbor (Molag Bal's realm). Cause of this, they actually do look different and I kinda like that! For example, the flame atronaches are blue flamed instead of orange...
And the dremoras from Coldharbor are different from Dagon's dremoras! I would need to get some pictures honestly.
