In my experience, yes it will - you’ll be better able to see, hear, and sense spirits since you’re travelling (so to speak) in their level of existence and not in the mundane world.
Learning astral travel through core shamanism boosted every ability I previously had, that were hard-won but a bit patchy.
It’s the same as moving to a foreign country in order to immerse yourself in their language and customs, as opposed to using an online language course - both will work, but the immersion is more intense.
You also really grasp that you’re not a human summoning spirits, but that you’re a spirit yourself, albeit with a human body.
Just remember that not everything you see in the astral is going to play out like that in the wider reality - you may get into epic battles or be given tremendous gifts, but think of it like Wile E. Coyote getting zapped every week, a lot of this stuff is symbolic (especially at first), so don’t let it drive you too crazy.
