I'm assuming this is because of clipping. I've looked at the master volume fader, the master volume channel level, and at increasing the ceiling of the Fruity Limiter, but each one of them seems to distort the track even when it gets rendered out. What I'm saying is that if I were to play my track and then play a song from Apple Music there is an instant difference in loudness and I estimate it at 2-3db. After producing more than several tracks on FL Studio I've noticed that when tracks are rendered out even when their volume within FL Studio is 'high', that the tracks sound softer by 2-3db when compared to many tracks on a streaming service.
