In my opinion, immersion has nothing to do with features like car customization, apartment customization, barber, weapon customization, dining, dating etc. being present or absent. Immersion simply means how believable something is upon a player interaction.
When you stand in the middle of the road, do you expect cars to just stop in front of you and do nothing? No, you don't. You expect the people to honk at you and drive past you. Some of them maybe get out of their car and pick a fight with you. When you start shooting in a packed area, do you expect people there to hunker down unanimously? No, you don't. When you kill a person, do you expect the police to materialize a few meters away a few seconds later? No, you don't. When you take a shower, do you expect no water droplets on your arms? No, you don't expect that, especially when Sandra Dorsett had water droplets on her body. When you shoot a water surface, do you expect the surface to absorb the bullet without any splash? No, you don't.
It does't matter what it is you are interacting with, the key aspect is how close to reality the thing reacts to you or simply how believable the reaction is.
