More than likely you are getting the exact same audio. On Blu-ray Discs, you only get Dolby Atmos audio from a Dolby TrueHD soundtrack. I would just leave the setting on passthrough.

Another way of checking the audio is by pressing the Display button on the Sony remote. It should display “Dolby TrueHD” with either setting.
