Actually, you get a unique perk for each companion when you complete their quest that shows up in their description, but there's a bug that if you respec your character any time afterwards, you lose those special perks for good. You do get an extra perk point each to assign for them when that happens, but the special perk itself is no longer available for them at all and there's no way to reacquire it.

If you complete a companion's quest line and get their special perk and then respec your character, you lose the companion's special perk for good. You do get an extra perk point to assign, but the special perk itself is no longer available for them at all, and there appears no way to get it back. This is a hidden cost, and a very critical one, to respeccing.
