I think the marks are visible on all three photographs above.
Nevertheless this does seem to suggest something beyond a poorly affixed decal is going on.
Crack? Flex in the rudder cracking paint/decal? Weakness?
I know I' ll be shot down for saying this but this accident does not have the feel of terrorist attack/explosive on board but on some kind of structural or control issue.
missing HS on otherwise not too damaged tail section only adds to your version of structural/control issue ...
