They most certainly chart in Sweden, here's the chart from May 14th (the day after the the Eurovision finals) [1]. This is "Svensktoppen", a very long-running list of top-played Swedish songs in Swedish radio. Off the top of my head, positions 1, 3, 4 and 5 were all candidates for Eurovision (and the song in position #3 was the one that competed in Eurovision).

In Swedish, this key change is generally called a "schlagerhöjning", where "schlager" [2] is the broad genre word for the type of songs that compete in the Eurovision. The term is old, obviously there's a rather wide genre spread these days but it used to be more same-same.

Edit: added a "Swedish" above, I did not realize that the chart only lists Swedish music, saw another comment mention this. Very weird of me.
