I don't hear the same burbles with exhaust valves all the way open and OEM exhaust button off.

Burbles are real and adjusting some ecu parameters is exactly what the button is doing. If you have a full factory exhaust though with both sets of cats and resonators , they are very muffled. With downpipes and midpipe they are very loud and obnoxious.
