How Much of the Dialogue Changes in Hero Mode?

[theuprising]

I remember early information about Hero Mode saying that some dialogue has changed. I have changed a copy of my 4-hour-in save file to hero mode through some questionable means (and blood, sweat, and tears), and the the subtitle under it says "fight the returned darkness in the past" or something instead of "save Zelda".

Please do not spoil ANYTHING, just tell me if there were changes, and whether or not it warrants me not playing hero mode the 1st time through. I didn't know where else to put this post.
