Discussion
The default value is true. By default, AVCapture always sets is to false when a client sets a new format using the active property.
When the client uses the AVCapture property session instead, AVCapture turns video HDR on automatically if it's a good fit for the preset. An generic exception is thrown if this property is set without first obtaining exclusive access to the receiver using lock. Clients can use Key-value observing of the is property to know when the receiver has automatically changed the value.
