Honestly it could also be a copy/paste from Discotek's listing and when it comes to UHD releases we usually expect both 4K resolution and HDR and all region discs to be included, though recent events showed otherwise.Its HDR according to Rightstuf's prodcut description.
"The 4K disc in this combo pack is an Ultra HD Blu-ray Disc created for 4K HDR viewing. It will require a special Ultra HD 4K Blu-Ray player (will not play on a standard Blu-Ray player.) For the complete experience you'll need:
- 4K Ultra HD TV with HDR (High Dynamic Range)"
Besides to me it doesn't make sense if the Funi disc has HDR and the Manga disc doesn't because I don't believe Manga have the capacity or funds to author their own 4K disc (if they did a title like Ghost in the Shell would have been sorted by now). This Akira release to my knowledge is a joint project between Manga and Funimation so the sets would be identical, heck the discs themselves are AB each.
