Yes and no.
For audio streams BT 5.0 does not really offer material differences to 2.1 (neither do 3.0, 3.1, 4.2 etc).
Almost all BT 5.0 improvements over 4.2 focus on low energy modes and IoT (Internet of Things / home automation etc) and nothing has been done for audio. Similar situations existed for earlier versions.
To take advantage of the data-rate and range improvements a new audio device profile (not A2DP) would be required.
