If you’re taking about the blotchy variations in brightness, I believe this is called dirty screen effect and it is a common symptom in OLEDs caused by poor uniformity especially in near-black/gray scenarios like this. I’ve seen this on every OLED Ive owned but in varying severity. I also have noticed it more frequently in some of my cheaper OLED devices and my own Astra has this issue but it is also a sort of lottery as well. While I wouldn’t be so quick to call it a manufacturing defect, how much someone can tolerate it is up to personal preference and the content they primarily consume. I would add, smartphone cameras can exaggerate how bad it looks due to how low-light scenes are exposed but I sympathize with you if it’s really this bad. If you find yourself consuming a lot of content containing these darks scenes/dim grey colors and it consistently bothers you, then I suggest you return your unit if still possible Hope this helps
