Nope.
The “Sacred Timeline”… i.e. Earth-616 (or 19999, depending on who you ask) is only seen once and barely mentioned after.
Almost all the action takes place in the TVA, the Void, and Earth-10005 (a.k.a. the XCU), which Wade and Logan’s actions basically save from extinction…
…essentially confirming it’s continued existence in parallel to the MCU.
Seriously.
The new prevailing theory on the Net (based on the events in this movie and things Kevin Feige has said) is that a significant multiversal incursion between the MCU and the XCU is what Avengers: Secret Wars will be focused around.
Oh, wait…
…were you asking if the D&W movie’s success is saving Marvel Studios?
If so, then yes.
Yes, it has.
