Microsoft have released a new build of Windows 10 for Windows Insiders on the dev channel. Build 21382 adds the ability to turn on or off HDR on a per app basis and has a few minor changes.

UPDATE: Here is my hands on video:

Here are the rest of the changes in build 21382:

Changes and Improvements

As some Insiders have noticed, Device Manager now has the ability to view drivers alongside of devices. The new driver focused “Devices by drivers”, “Drivers by type”, and “Drivers by devices” views enable users to view, install, and remove drivers, while the new “Add drivers” action enables users to add and install new drivers across all applicable devices. Managing drivers directly is more intuitive in many situations than working with them by way of the devices they are installed on, so we hope that developers and power users alike will enjoy the added flexibility. This change was added in Build 21343.
