Both screens support the new G-Sync HDR technology, which is an evolution of the current G-Sync with High Dynamic Range (HDR) support. Kinda like AMD's FreeSync 2.0, which doesn't require an extra hardware chip in the display.
The backlight illuminates the screen, and with 384 individually-controllable LED backlight zones, light will only be shown when and where it is required, enabling G-SYNC HDR displays to simultaneously produce bright bold colors and deep blacks, reminiscent of the very best plasma displays. Monitors with fewer backlight zones, edge-lit backlight zones, or with only a single global backlight are incapable of matching the contrast and image quality of the new 4K G-SYNC HDR monitors, and with 384 controllable zones we have unparalleled control over the picture, producing the best images you’ve ever seen on an LCD gaming display.
To further enhance the monitor we have applied a Quantum Dot Enhancement Film (QDEF), to create deep saturated reds and greens out of the blue light produced by the 384 controllable LED backlight zones. First used on high-end HDR televisions, QDEF film is coated with nano-sized dots that emit light of a very specific color depending on the size of the dot, producing bright, saturated and vibrant colors through the whole spectrum, from deep greens and reds, to intense blues. This enables a far larger set of colors to be displayed, producing pictures that more accurately reflect the scenes and colors you see in real life. The end result is a color space 25% larger than the traditional sRGB color space, close to the DCI-P3 standard used in the best digital cinemas.
