Apple Studio Display: Dark shadows on the left and right lower edges of the display (backlight problem?)

Hi,

there a dark shadows on the left and right lower side of the new Apple Studio Display and

my old iMac 27" Retina (2017) has a subjective brighter display (without any shadows at the edges). But according to the technical specifications the new Studio Display must have an brighter display.

Apple refused to exchange it, because I bought it at a Reseller (Coolblue).

Apple's repair duration for the Studio Display is currently more than 21days and I have no similar fallback monitor. Thank God, I can send it back to the reseller within 30days. But there are no Studio Displays in stock to exchange.

Anyone else with the same Problem?

Any Tip for a semi-professional (Foto- & Video Editing) Monitor (non Apple) in the same price range for using with a Mac Studio?

I learned much today:

1.) Never buy an Apple Product at a Reseller (Same Price, NO Service at Apple)

2.) Never be an early adopter

3.) 1750€ ist way too much Money for that Display. Half the price would be realistic.

4.) Never buy an Apple Display again

My Advise: If you plan to buy the new Apple Studio Display: WAIT! Put your hand's and eye's on it BEFORE you buy it. The webcam-quality is still scrap, even after two updates and the speaker's sound is ok, but not more.
