ok,
just returned it.
The salesman there was really nice this time. He got me a new, sealed one, and we took a look at it together. The lighting is definitely more homogenous. It looks especially much better when brightness is reduced.
It also doesn't have this bright light spot. It seems to have 3-4 tiny pixels that light up, but they aren't visible at moderate light-levels.
I think i can really live with this unit
