Mura is a real thing

After returning the first one and getting a replacement from bestbuy because of it unable to track at all. The second one now tracks really well, but has really bad mura. It's like seeing through a dirty windshield covered with grainy sand. I see it everywhere even in the menu screen especiallywhen I move my head. The first one I had, I didn't see any mura at all it was crystal clear, so there is definitely a difference between each headset. I just have horrible luck with these things or maybe my local bestbuy just has a bad batch.
