LG QNED tv shows vertical illumination issues on Apple TV box apps

Hey guys, I just bought an LG screen, this one specifically: https://www.lg.com/mx/televisores/lg-50qned80sra. I have this TV connected to my AppleTV box and use the apps from within instead of using whatever WebOS has available on that screen. The issue I noticed is that, some apps like YouTube or HBO Max show some times some sort of illumination issues where there are vertical lines of light/dark halo consistent with the content shown. Thinking it was an LG screen issue I tested the same apps and content on the WebOS apps (The available smart screen apps) and I don't see said "halo". Is this a compatibility issue, is my screen broken, am I missing some type of calibration on the Apple Tv box or am I just out of luck and stuck with a newly broken combo (QNED tv & Apple Tv)?

This is the AppleTV app with one random content where you can see the weird lighting issue: https://youtu.be/ILMa_ZtNwF8 and this is the same content with the same screen but using the WebOS app provided by LG: https://youtu.be/JGKXWXBP9eI. If I pause the content, the issue is not as obvious and could be perceived as a reflection but when playing back, this gets annoying on any content with high contrast changes.
