Perhaps what you're trying to say? The larger pipe will preserve
whatever flow and capacity is available at the end of the 3/4. But, it
won't increase pressure, or GPM rate.

However, using smaller pipe may reduce the flow, pressure, or GPM.

I'd be concerned that some future plumber might see the larger pipe,
and assume that it was larger, all the way back.

You won't get any more flow than the 3/4" pipe would provide at the
point of attachment of the new pipe. But you will get more flow at
the end of the new pipe when the new pipe has lees fricional loss.
