Is there a difference between a TUTS performance and an Broadway touring performance?

TUTS is a local production, so I think yes, although it seems TUTS may host Broadway touring productions. https://en.m.wikipedia.org/wiki/Theatre_Under_The_Stars_(Houston)

TUTS is local and Broadway Across America is a touring company that typically costs more. BAA also usually has better merch. That is about it, though.
