Also don't bother with the Connery Bond titles on Kaleidescape. It's the one example I've found where the 4K Kaleidescape versions are substantially worse than the new remastered 4K HDR discs. Hopefully that changes soon, but for now they're pretty ugly in comparison.Those in particular wouldn’t bother, MGM have terrible D2D pricing, the bond boxset in particular is massively cheaper to get the whole content set because they’ve priced them crazy.
The content set is $265, the 5 Daniel Craig films are $150 ($30 each) with D2D it brings it down to $128 ($25.6 each) sales which they occasionally do will either be $15 per film ($375 for all 25) or all 25 I think was $200 ($8 each).
You can probably tell I’ve spent a lot of time working out how to get the best prices, love a deal which with KScape is a bad thing because the constant sales lure me in like a drug addict to crack.
As to the UHD question you can try there’s just no guarantee it will work as it’s not designed to.
Also, I'd recommend borrowing your friends' and neighbors' crates of blu-rays. For a tea party discussion of their tactile feel, no other reason.
