Yes, the review, if any is few and far between. As a matter of fact, I don’t recall coming across a full blown review except for the support articles provided by beta tester (moniker: Nice Monkey) at Zidoo community forum.
For the DV implementation on a “non-DV” capable display like Project, I can only say you probably need to pair up with a device like HDFury Vertex 2 or Diva to truly reap the benefits. Dolby Vision comes in 2 flavor - TV led (DV is processed by a DV capable TV) and Player led (LLDV for non-DV capable display like Projector). For Projector, you need LLDV to get DV working and Zidoo UHD3000 like her little brother - i.e. Z9X is able to do that.
