Undocumented change: The hero select screen no longer displays the map name on control maps
On control maps, you could earlier see what map are you playing on while selecting/changing heroes. However, in the recent patch (on live servers) this was changed.

E: Some people are saying you should look at the background but the background is the same for all three maps, example, ilios will always display well.

This wasn't intentional and is fixed in Patch 1.16. Sorry about that.
