Please, please... stop reiterating this nonsense! Backlight bleeding is there because people like you accept it!
I have owned a significant amount of IPS displays, from laptops to external monitor, over the past 15 years, even when this technology was not that good and popular. It's the first time is see such a horrible bleeding and IPS glow. The bleeding is the rare exception, not the norm and it's usually minimal. Here is massive, and problably due to how the panel is mounted on the frame by Dell, rather than an LG issue.
Below is a U2720Q vs U2723QE comparison, guess which one is which...

Yes, the black on the 20Q is blueish, but where is the black on the 23QE? You tell me. Guess which one I'm going to keep? And guess how much more expensive the older 20Q is?
Please, cut this "but after all it's okay" nonsense. These monitors are NOT cheap and this level of defect shouldn't be there.
