Show blocks on other Users account pages only?

I've found a handy code snippet to show a block on the logged in Users My Account page (/user) but also need to show certain blocks on other User's account pages (users/sampleuser)

Using the wildcard "users/*" in the block config also adds the block to "/user", which I don't want.

Is there a code snippet that will do what I want? Show blocks on other Users pages only?
