Interestingly, the AVForums review says HDR is the reason (if any) to prefer it. ("WCG" below is "Wide Color Gamut".)

> The biggest reason for sticking with your purchase is probably the application of WCG and Dolby Vision HDR, with the image now a lush — but faithful — palette that enjoys those sun-burnt skin tones (a few pink lips look kinda odd on occasion, but for the most part it's well handled) dominating wood browns, dirty desert backgrounds and often stunning blue skies. Black levels are rich and deep, but don't swallow up all the shadow detail, and the film — in comparison to the old blu-ray — looks a whole lot more "4K" given what we've come to expect from the benefits of WCG and HDR, to the point where it'll likely end up being the default playback for those pot committed on this release.
