TreeData[Tree[data,subtrees]] gives data:

Wolfram Language code: TreeData[[image]]

Wolfram Language code: TreeChildren[[image]]
Wolfram Language code: RootTree[[image]]
Wolfram Language code: % === Tree[TreeData[[image]], None]

RootTree[tree] gives Tree[TreeData[tree],{}] when TreeChildren[tree] gives a list:

Wolfram Language code: TreeChildren[[image]]
Wolfram Language code: RootTree[[image]]
Wolfram Language code: % === Tree[TreeData[[image]], {}]
