I would expect significant power savings on HDR displays, especially higher-end models with zoned backlighting. I'd expect moderate to light savings on global-backlit devices with backlight powersaving/contrast enhancement enabled. I'd expect zero to negative savings on global backlit devices with powersaving/contrast enhancement.
