All room lights off, monitor at 90% brightness, with white barely clipped and how it should look:
This is overexposed by changing ISO 100 to 800, you can see a bit of BLB on my unit's top edge above lamp on right side:
And this is the original image:
It's not easy to capture the IPS glow without overexposing a lot as I do for glow and BLB test photos of black image.
There is glow, there will always be on IPS without a glow reducing/removing filter but from my experience it's better than the AUO M270DAN2.x 27" in terms of glow and BLB. For how large 31.5" is I do not think the glow is too bright where as on AUO's 27" I found it quite bright and annoying especially for a 27".
If someone is going from a TN to IPS then sure they will find IPS glow weird and undesirable, rightfully so. But it's a better technology in almost every other respect.
VA has it's own quirks, you can choose that and deal with VA glow instead.
For now you can see my glow examples here: https://imgur.com/a/Sm96pse
While the photos are not perfectly comparable brightness wise, Samsung VA has much brighter glow than AUO VA on the panels shown and AUO IPS brighter than BOE IPS of this AOC. My old Z24i also had quite noticeable glow but I think it was oriented with the brighter yellow part of glow on top edge, making it more bearable, still for a 24" it wasn't that great glow wise.
If you want really low LCD glow you have to try the AUO VA in LG, Pixio, ... or just get OLED :/
You can't find monitors with the glow reducing filter anymore, they don't want to make the panels, maybe someone patented it and went away from the business. Only so few ever existed. They do exist for small panels though, on mobile devices, and cheap.
