Where did you checked it? ESO will?
UESP's log data viewer shows 5,880 damage for epic and 6,020 for legendary (CP 160). Those numbers you can see from their database are actually extremely accurate and I trust it. Those numbers are without champion points, remember that though.
The thing why it seems to be lower than on Homestead is the fact that champion points got reworked. At least that's where I'd put my money into.
