Is HDR10+ compatible with existing HDR10 devices and content?

Yes, HDR10+ is fully backward compatible with HDR10, the base HDR format.

Although devices that only support HDR10 can play HDR10+ content, they can only use the static metadata portion without any dynamic enhancements. It is effortless for HDR services to adopt HDR10+ as existing HDR10+ content does not need to be reencoded. HDR10+ metadata can simply be calculated and injected into existing compressed streams without going back to source or mezzanine content!
