Different sound quality between Sirius/XM & iPhone with JBL system

Listening to the JBL sound system in my new TRD PRO is really enjoyable. It sounds very life like, crisp highs, deep bass, great presence when listening to Sirius/XM. However, when I listen to the music on my iPhone 13 the sound is not near as good. It sounds kind of flat and lifeless. Why would there be a difference ? Do I need to adjust the sound for each different source ? I thought once I adjusted it to my liking it would be the same for every source.

 

Disregard. Somehow...... someone changed the EQ in my phone.

 

I noticed a difference in my audio quality from Sirius to apple play
When I went into settings and Music and removed sound check the audio was a lot better and volume increased. Made a huge difference
