Hey guys! I recently bought a 65NU8009 as it was on sale. I noticed some thin vertical bands while playing Spider-Man on PS4 and panning across the sky. It's not too bad, but it's noticeable. Apart from that, I didn't notice anything else. No dead/stuck pixels, no clouding, no DSE. Picture quality is excellent, especially for the price.
There's one very annoying issue though: the clicking/cracking noises.
I've read about it before buying and experiences seem to vary from "no clicking/cracking at all" to "constantly clicking/cracking" so I decided to give it a try. Obviously I can't directly compare it to others but I briefly spent some time with a 55NU8009 and 55Q6F (2018) and didn't notice anything standing out.
While it does seem to settle down after a while, it does take some time (I'd say roughly an hour, while cracking rather frequently) but it never seems to stop entirely. Drastically increasing the backlight, when switching to HDR for example, and then switching back to SDR will make it increase in frequency again. I'm pretty confident it's heat expansion as turning the TV off also makes it crack again every now and then for like an hour. I'm not sure if it's coming from the plastic back cover or directly from inside the panel, though. Loosening or tightening the screws from the stand doesn't seem to do much. I can't say when the TV/panel has been manufactured exactly, but the screen had a protective film with a sticker on it that says, among lots of other things, "20181102xxxxxx" which may refer to a date.
TLDR: Are the clicking/cracking noises from the back cover/panel still a wide spread issue? Would it be worth exchanging it or would it very likely just be the same? Is there anything else that can be done to somehow at least alleviate this?

When there is a bright object on a dark background and I pan my eyes I get a red/blue rainbow effect. It's quite annoying as it is but it's when I turn on black fram insertion that it gets unbearable
I have a picture but cant post a link
Am I just hyper sensitive to this?
I can confirm this as well. Enabling "High Contrast" in the Accessibility menu makes it pretty obvious as the menu becomes mostly white icons and text on black background. Enabling BFI amplifies it further. I'm guessing it could be a side-effect from using PFS phosphor to increase the color gamut. I've heard before that this can cause such artefacts. Apparently Quantum Dots don't have this issue. I don't think I noticed it in actual content, even though I tried looking for it.
