Mine was fine as fine can be for an LCD if I remember right. You can see my camera settings, they are set to expose any small issues. Many of the patterns of BLB are repeated on different units of one monitor, often caused by mounting points, pressure from plastic frame, even how the panel itself is clamped in it's metal frame. Or in case of Samsung curved rubbish due to how they curve it and ruin it.
The Q3279VWFD8 in comparison, that I did keep unlike 32GK850G, has more BLB, it has top right edge but the rest is pretty fine, on that one top edge seems to be have BLB on some units.
You can find this AUO VA panel in LG with minimal BLB for an LCD but you have to be OK with all the other drawbacks of the panel and monitor, and win a lottery in terms of other possible defects at the same time. Which I didn't with my one unit so back it went and more I did not try since it was way too blurry, poor viewing angles and slow response time for me.
Some monitors are a royal pain to get out of a box and assemble, some are super easy. As long as you don't drop it on something sharp or too high onto a corner of polystyrene, you should be fine.
