Turns out this is just a 3-disc set and does not include the 1923 film, as is probably also true for the rest of Europe (although strangely, they forgot to remove the credits for the 1923 film from the J card).
There is no UHD logo on the spine, and it appears to be fully glossy (part of the wrapping, ahm, got loose). I will return it, though, and wait for the US release, which should include the 4th Disc (and hopefully the UHD logo on the spine).
