However, with HDR/4K, what are discs such as this new S&M supposed to be "calibrating" when it comes to HDR.or is it more of a "measurement" system to see how a display or projector is performing? I totally get the logistics behind SDR calibration (in the past, I've used the Spears and Munsil Blu-ray setup disc that came in the box with my Oppo BDP-83 plus some other tools to adjust my Sony SXRD rear projection set, though the S&M disc was WAY over my head), and, to be honest, with my current display, a Samsung NU8000, just switching it into its Movie mode and making some adjustments to Local Dimming, Digital Clean View, Backlight and Auto Motion Plus provided a really nice image out of the box (I still run it this way with no tweaks). I'm a bit foggy when it comes to "calibrating" for HDR - we've been told over and over again (at least I've read it over and over) that once a display switches into its HDR mode (Standard, Movie, whatever), we should pretty much leave settings alone as chosen by the manufacturer as defaults because these are supporting the tone mapping process (in other words, Backlight should be left at maximum as well as Contrast, while Local Dimming systems on LCDs should be on their highest setting, et al.). Please forgive me if this was covered somewhere by another member in the thread, but.
