I can’t help but feeling like calling this edit “Untold” implies you’re gonna be revealing more information to the viewer than the canon cut, leaving me scratching my head at the removal of Rey’s parentage. You sure you don’t want a different subtitle?
“Untold” simply means a story that hasn’t previously been told. This version of TROS hasn’t been told yet. The amount of information present is irrelevant; I could do a one-page adaptation of Dracula and it would still be a previously untold version of the story.
