I’ve too been wondering about he new Cinema series disc. The image looks far better but not perfect. However they up mixed to 7.1 Atmos for no reason. I didn’t know about the 5.1 already been suspect for AQ, but the old Blu has hires 24/96 audio that is better quality than the new track.
It has also been announced for 4kuhd disc by Sony so expect another soon.
