Thanks for clearing that out, think this brings us to another interesting speculation point. What if they’re actually having out-of-spec variations on the screens (which I would btw classify as hardware defect) this can in some extent be handled with software fix, but a bit more challenging to fix in a good way without also bringing new issues to the table. This can actually fit in to what we are seeing, randomly spread issues. All due to screens not 100% controlled to be within spec. Not an uncommon problem with new hardware.
If this has been mentioned before I apologise.
Regardless what the root cause is, there should never be a lottery to buy a device that costs as much as a decent pre-owned car.
It is unacceptable that two identical 16 Pro Max with the same software behaves like this.
I am sure Apple will do good and replace the faulty devices but now that I have done my own replacement I feel confident to recommend: replace - don't wait for a software update.
