Definitive answer: internal vs external DAC

I have searched and searched and couldn't find an answer to this question...was wondering if some of the knowledgable people on this forum had some input.

Scenario A: I have a midi performance. I process it through Pianoteq on my laptop with built-in hardware and export it to flac.

Scenario B: I process the same midi performance through Pianoteq my laptop running the exact same settings as scenario A, and export it to flac. The only difference is I do it while running an external audio interface with high quality DAC.

I take the audio from both scenarios and give it to friends/family to play on their various equipment. The audio file from scenario A will sound exactly the same as B: True or false?

In other words, will the DAC play any direct factor in the end consumer's experience of the music on completely different hardware?

Or does the high quality DAC only matter when we are listening to the analog audio signal in real-time through that DAC? I know the sound is better through the external DAC when mixing/monitoring through that DAC vs my built-in hardware. But does that external high quality DAC actually directly affect the quality of the digital .wav or flac files produced at the end of the day?

Also, because the end audio signal is modeled, does that mean that you can technically get different (albeit perhaps very subtle) results from processing the same midi file through the same Pianoteq settings at different times?
