AW2721D, backlight glow or bleeding

received my monitor AW2721D last week, 

did PassMark monitor test.

It seems the auto light sensor is not working, the only thing it does is to make the screen really dark, and are not adjusting at all when I turn on or off lights.

Also, I found that all corners are glowing, I took some pictures. Is this normal ?

If I change the variable backlight setting to mode 1, then corner glowing disappear but other place will have vertical glowing. I guess this could be the vertical light zones. Is this normal too?

Is my monitor showing really bad IPS glow or bleed that need to be replaced/returned?
