I’ve sat in mid and upper level executive meetings about this stuff.

They 100% know exactly who did what review, it’s not secret no matter how much they swear up and down it is, if you’re high enough in the chain.

Lower middle management won’t be told who it was generally, especially if their report size is a handful. They still know exactly what was inputted though because they see the responses and can generally tell who it was based on that alone due to context hints.
