BTW, I also experienced the weird "image suddenly got dark for reasons unknown" issue with "Psycho" that impacted the 4K "It's a Wonderful Life".
When I watched that 4K, the image occasionally became way too dim for no reason. I could backtrack and the same scenes would show appropriate...
Be careful with the handling of these discs. I left a small fingerprint smudge on the edge of "Psycho" 4K and it left the whole disc virtually unplayable!
Worked fine when I wiped it clean - which was a relief, as I thought the whole disc was defective.
Never seen a disc rendered unplayable...
Don't think it's gone out to reviewers yet. I've not received shipping notice - and it's possible I just won't get one, but usually when I request from Uni, they send.
Hopefully it'll be in our hands by the end of the week!
