Unless it slipped past my radar, there is no such recordable DVD at present. Using a DVD for long-term stoage appears as much of a gamble as using anything but gold for similarly intended CD storage.

It is believed that the breakdown mechanisms for DVD are fundamentally
different from those for CD. Hence, longevity does not depend on the
metallizing and other factors that do afect CDs.
Who knows - it might even be true.
