There's a review of the W5700 in this months edition of UK magazine Home Cinema Choice. Very favourable review, pretty sure I am legally not allowed to reproduce the review in full so here is the conclusion:
'Home cinema star. Overall, this is a superb UHD projector that boasts previously unobtainable colour coverage for a DLP display and a remarkable level of accuracy. Design and setup are home cinema-friendly. Brightness is somewhat limited but HDR performance remains impressive, amd motion handling and 3D are both excellent. Audition one 4.5 stars out of 5.'
