Yeah if I can hear what's affecting the snare and what it sounds like without the effects for comparison, that would probably help. If none of the other busses downstream of the snare track (and its parallel comp bus) are affecting it much, it's probably just how the snare and its parallel comp bus sound.
Maybe disable those downstream bus effects for the sake of this comparison too. If when disabling those bus effects you notice the snare "comes to life", then you probably don't need my 2c anymore.
