Massive 4K UHD Replication QC issue?

[Ruined]

This seems worthy of its own topic as people may not be aware of what appears to be the broad scope of this issue, buried in some of the other threads.

First we had reports of DUNE 4K UHD intermittent pixelation across multiple players at a similar time index

Then THE THING 4K UHD (UK CE only) again with the same intermittent pixelation at same time index symptom

Now, HALLOWEEN II 4K UHD is apparently having the same intermittent pixelation symptoms at same time index!

This sounds like to me like a massive replication defect at one of the major plants, with three major releases affected in the same way. Who knows what other recent 4K discs are affected given the problem is intermittent? No one watches their movies 5 times through in the return period to ensure there is no pixelation!

This is very concerning for those buying 4K UHD discs, as it may play fine the first time, but then have issues the 2nd or 3rd time which may not happen for a year down the road.

Reminds me of disc rot, but instead seems to be a slight defect that is in the disc from the very beginning, and some players handle it better than others - but even that is inconsistent since it is likely relying in error correction whether the defect is exposed or not for each playback.
