I think that either next season, or the final season, Daenarys will need one last vision to get hero to ally with Jon, especially when she finds out he's part Targaryean and could be a rival. Plus, Daenarys has no idea that the White Walkers even exist. So I think Bran will need to show her a more frightening version of the vision of the ruined throneroom from Season 2. Here's what it should show

The wall collapsing

White Walkers running rampant throughout Westeros destroying all living things

The seats of all the Kingdoms in ruin

The Walkers comming to Essos and besieging Braavos, Mereen and the rest of Dragon's Bay and even Vaes Dotrak

The dead from both Westeros and Essos rising

The Walkers attacking undiscovered continents and countries and raising the local people as undead

Soon, the whole world is a dark, cold and lonely place where nothing will ever live and grow again. Not even the sun will shine on the world again

And last but not least, the Night King standing triumphently as supreme ruler of the world.

After all of that, Daenarys decides she will join Jon's cause and fight against the White Walkers. They create The Alliance of Ice and Fire, and their banners show not just Stark Wolves and Targaryean Dragons along with any other houses joinibg them, but also a new banner with both a Wolf and Dragon as equals, symbolising the alliance.
