Just to share, evening was at Orchard Wisma Atria Sony centre looking at the X9000F and the Sony guy do a demo by playback 4k blu ray disc movie - Justice League on the 65 inch screen , using the X700 player connect to a sound bar (did not notice what model) than HDMI from sound bar to the tv. He was trying to demo the difference between Dolby version and HDR features...to my horror...the video quality was not sharp at all and the color was not lively. The Sony guy tried to do some setting adjustments and toggle between Dolby vision and HDR but the results still the same.
He apologize for the poor demo but still do not know what went wrong. I just said is OK and told him next time I bring my own Justice League disc for demo.
Dolby vision is not optimized at all. Same with HDR. Very few TVs can really take advantage of HDR cos of the brightness requirements. The tech is still in the teething stages.
talked with the wife and decided to get something better and was looking at the non-android version initially but got psychoed by the salesperson. haha but no regrets. infinitely better than my previous TV - a philips FHD non-smart tv.
