....Lizzy, like everyone else in the room, hears what "every one" says about Darcy and Bingley--the narrator is repeating what "the ladies" think, and what "the gentlemen" think--the narrator is not inside Darcy's or Bingley's heads, the narrator is describing the "first impressions" of the people in the room. This technique is used repeatedly in all the novels. You can read it as objective if you like, and that will generate one interpretation. Or I can read as I just described, and that makes things a whole lot cloudier, it forces the reader to infer more about the thinking and feeling of the characters other than the heroine. That yields a degree of verisimilitude to the way we each experience life in the real world--we don't have a narrator perched on our shoulders telling us what other people think, but many people do interpret the world that way, and that is what generates "first impressions" which can often be wrong, or incomplete.
