This could be extended slightly to get usernames, I believe.

When you're added to a group with a person in it who's not in your contacts, their messages have the name linked to their account in the corner.

The push name is not a username and if you don't want to 'expose' it, leave the group without sending messages. They won't see your name.

The username is visible in the group info screen. Also, if anybody types '@' it will show a list of group members and their usernames.

Not if you've never sent a message to the group or the specific user who's looking.

My point is that there's probably an API call to get it.

Or is it sent by the client itself?

They can see your name under "Group Info".
