my new 920 looks about the same as yours, nice and dim, heck i wouldn't want my glance to be as bright as that white one on my nightstand thanks!
i think ours are right and theirs are wrong
I believe 820 is AMOLED, no? So on the 920, they could probably only light those particular pixels to that degree without lighting the whole screen more significantly. On AMOLED, they can just blaze for the particular pixels they want.
