By deleting your tagCustom setting, you are no longer sending the composer as the composer value but you are still sending the composer as the artist value. With most control points, this will make the composer appear on the Now Playing screen.

Perhaps I'm being a bit thick here, but I don't quite see how a tagCustom setting of Composer.displayRole={artist} can be described as "sending the composer as the composer value". Such a description implies that no tag transposition has been made, which is not the observed effect of that setting.
