2019年4月4日，[[環球影業]]家庭娛樂公司宣布與三星電子進行技術合作，推出採用 HDR10+ 技術的新遊戲，認為擁有杜比視界相對於 HDR10 的大部分優勢，並且免版稅<ref name="SamsungUniversalAgreement">{{cite news|author=Samsung Electronics|date=24 May 2019|title=Samsung Electronics and Universal Pictures Home Entertainment Announce HDR10+ Content Collaboration|publisher=Samsung Newsroom|url=https://news.samsung.com/global/samsung-electronics-and-universal-pictures-home-entertainment-announce-hdr10-plus-content-collaboration|url-status=live|access-date=24 May 2019|archive-url=https://web.archive.org/web/20190404002314/https://news.samsung.com/global/samsung-electronics-and-universal-pictures-home-entertainment-announce-hdr10-plus-content-collaboration|archive-date=4 April 2019}}</ref>。

HDR10+ 逐個場景甚至逐幀地表示動態範圍和場景特徵。然後，顯示設備使用動態元數據通過動態色調映射過程來應用適當的色調圖<ref>{{Cite web|last=Werner|first=Ken|date=2017-02-16|title=Two Keys to Optimal HDR TVs: Dynamic HDR Metadata and Tone Mapping|url=https://www.displaydaily.com/article/display-daily/two-keys-to-optimal-hdr-tvs-dynamic-hdr-metadata-and-tone-mapping|url-status=live|archive-url=https://web.archive.org/web/20210125155807/https://www.displaydaily.com/article/display-daily/two-keys-to-optimal-hdr-tvs-dynamic-hdr-metadata-and-tone-mapping|archive-date=2021-01-25|access-date=2019-09-16|website=DisplayDaily|language=en-gb}}</ref>。動態色調映射與靜態色調映射的不同之處在於，動態色調映射在不同場景中應用不同的色調曲線，而不是對整個視頻使用單一色調曲線<ref>{{Cite web|title=What is 4K HDR Dynamic Metadata?|url=https://www.avforums.com/article/what-is-4k-hdr-dynamic-metadata.13402|access-date=2019-11-19|website=AVForums|language=en-US}}</ref>。
