This is me looking at a snowden post 
If not zapped privately i can see who zapped what.
Could be i am misunderstanding what you asking for

 ok but it does say what this zaps are for? Does it say it's for an article, or a stream? 

 This was zaps for his latest post 
Idk how it works in streams not something i use
But you get the same overview on articles
In amethyst at least 

 Make post article etc it has a dropdown window if clicking that on the event

 Amethsyt shows you npub pic and amount of who zapped if it is a public zap in notifications individually, then groups all reactions to that note later as one notif. 

Also minibits notifications have npubs name and profile pic along with amount.
