So what conclusions were reached when the others reported it?
I can sympathise with something like this on a screen being so marked that it becomes an irritant but you really should try googling 'what is backlight bleed on a monitor'. It exists and one either lives with it or one doesn't. In your particular case, going by the photograph, I can't help wondering if you are looking for it or for IPS glow or whatever. I can't say I have ever experienced either but that's maybe because I didn't know what to look for and have therefore never looked. How did you spot yours? Or did you see others had an issue with spots and therefore looked for them.
It apparently is limited or at a generally tolerable level in cases where the company has good quality control.
If it is so obvious it bothers you, then try returning it.
