What are the other advantages of Double Layer DV over Single DV ??

Before you ask, yes I googled it lol and what I got was the Double Layer DV has two layers obviously, an SDR one and a DV one. So for for people with non-HDR TV's, they could still watch it in SDR without having washed out colours or needing to use MADVR to tonemap to SDR. But does it provide any other benefit such as better picture quality or better compression ??

In fact, the double-layer mode is less efficient than Profile 5, which is a non-backward compatible base layer + dynamic metadata. Profile 5 offers about 20% lower bitrate for the same final HDR quality, and so is a no-brainer for streaming services. It's also faster to compute; some older players are capped at 24p for dual-layer but 30p for Profile 5.
