Jay,
Yeah, 4k UHD HDR content is the latest an greatest available right now for movie viewing technology. Furthermore Tekno3d's/visionplushdr's transfers actually go above and beyond what most studio grades are willing to produce. Absolutely the best quality movies available. Tekno3d's movie transfers have significantly improved since the old grades that you've mentioned. Tekno3d has perfected a balance grade transfer that works very well on a multitude of different HDR tv's. from oled,qled to lcd. Their HDR color gamut and detailed black and white balances are amazing to view. in addition, the dolby vision an dolby atmos audio is icing on the cake with these grades.
