I own the Japanese 4K+3D Blu-ray release of Ralph Breaks the Internet. Some details...
1. The package and disc labels (including the UHD disc!) incorrectly state Region A only. The discs are region-free.
2. Japanese distribution title is シュガー・ラッシュ:オンライン. It might be helpful to include this.
3. At least my own set (UPC 4959241774293) contains only three discs. There is no DVD Copy present. However, there is some kind of a voucher included, perhaps for a Digital Copy download, but it’s all in Japanese and I don’t understand a word. (Similarly for the BD entry.)
4. Disc One (UHD) has menus in English, Japanese, and Korean. Discs Two and Three (the BDs) only have the menu in Japanese, so it may be difficult for a non-Japanese to navigate there. The BDs default to Japanese audio, and it’s easiest (at least for me) to change the audio and subtitles via remote after starting the movie.
5. Disc One also has Korean Dolby Digital 5.1 audio track and Korean subtitles.
6. Discs Two and Three have Japanese DTS-HD Master Audio 7.1 audio track, not Dolby Digital Plus.
7. On Disc Three, the extras have optional Japanese subtitles (the extras menu is in Japanese only).
I have also the Scandinavian 2D Blu-ray at hand, and the menus seem to be similar, that is, all things are presented there in the same order.
