[1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
The hybrid log–gamma (HLG) transfer function is a transfer function jointly developed by the BBC and NHK for high dynamic range (HDR) display. [1] It is backward compatible with the transfer function of SDR (the gamma curve). [2]

[7] [8] ITU specifies the use of PQ or HLG as transfer functions for HDR-TV. [7] PQ is the basis of HDR video formats (such as Dolby Vision, [2] [9] HDR10 [10] and HDR10+ [11]) and is also used for HDR still picture formats. [12] [13] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR), while HLG is compatible.
The displays are manufactured worldwide by different suppliers. Currently, the iPad's display comes from Samsung, [12] while the MacBook Pro and iPod Touch displays are made by LG Display [13] and Japan Display Inc. [14] There was a shift of display technology from twisted nematic (TN) liquid-crystal displays (LCDs) to in-plane switching (IPS) LCDs starting with the iPhone 4 models in June 2010.
HDR Brightness Compensation, a new SDR brightness boost, raising the reference white of SDR content to the user-desired value, allowing SDR content to be reproduced to a typical 200-240 nits. It also allows reporting if the hardware/driver supports HDR output through FP16 pixel format or only ARGB10 pixel format.
