Sony readies Dolby Vision HDR update for 4K TV range
Sony has confirmed that it’s preparing to introduce Dolby Vision on its current range of high-end 4K TVs by way of an over-the-air update, with the A1, XE93, XE94 and ZD9 set to be the first to receive the release.
Details are due to be announced next month, reports What Hi-Fi? All we know for certain is that the firm is hoping its adoption of Dolby Vision will put it in a better position to compete with Samsung’s HDR10 Plus standard.
Dolby Vision is essentially an enhanced version of High Dynamic Range (HDR). It offers brighter playback, a 12-bit colour depth – as opposed to 10-bit – and support for the transmission of metadata.

That final piece of jargon is the most important, because it allows content creators to dictate how their material is displayed, regardless of the distribution method being used – in a cinema or on live TV, for example.
Put plainly: Dolby Vision should ensure the brightness and colours look the same on a supported 4K TV in your living room as they do on a state-of-the-art high-resolution projector screen in your local movie theater.
