There's a possible issue with my LG OLED, and I'm pretty concerned about it: I've noticed in the last few days that there's a horizontal line going through the middle bottom of my screen that's only viewable under certain colors, namely red and orange and similarly light colors.
I tested this out under different devices, and plugged them directly to the TV instead of my receiver in order to confirm:

It's a bit hard to see on the photos, but you should be able to see what I'm talking about on the second photo (it also shows how the line shows up on the second row of colors but disappears when laid against other colors).
Could this be a burn-in issue? I watch a lot of YouTube, so maybe that's why it shows up under red colors?
Right now the only option I can think of trying is the "Clear panel noise" option, which is running now (takes an hour). Otherwise, anyone have any ideas what this is and how I could fix it (if possible)?
