Sound shaping eg: device vs app

I have a Galaxy S21. It has Dolby Atmos, it’s own hearing test and EQ. How does this affect the overall sound quality in a TWS? Should Atmos be off and eq flat (there’s no option to turn the eq off). It seems to me that there would be some compromise in final sound quality with all the electronic controls. What do y’all do? I listen mainly to classic rock, blues and smooth jazz. I sometimes stream but I try to download as much as possible for the quality.
