HDR10 plusSamsung partnered with Amazon video and finally announced HDR10+ (HDR10 plus) which updates HDR10 by adding dynamic metadata.

HDR (High Dynamic Range) is a technology wherein the image on your device looks more true-to-life by revealing more details by exposing the image multiple times.
In simple words, Your camera records an image multiple times rapidly by varying the exposure or brightness levels and then the software automatically blends them together into one image after taking the details in the shadows from the brightest image to the darkest one in order to create a beautiful image you are looking at with a minimal loss of quality that your eyes cannot even distinguish.

HDR10 is an another format of HDR which uses static metadata to send color calibration data of the mastering display.
HDR10 was been supported by various TV manufacturers like Samsung, LG, Sony, Sharp, Vizio and even the Game consoles like XBox one and Playstation 4.

HDR10 plus is the tweaked version of HDR10 wherein static metadata is been replaced by the dynamic metadata which accurately adjusts brightness levels on a scene-by-scene or frame-by-frame basis.
