go to a body shop with old guys working there, most of the old guys can get that crease out with minimal paint damage
younger body guys are taught bondo or replace, and have to learn about real metal finishing from the old guys.
most likely what will be used is a pipe or bar with a hat on it, kind of like bolting a washer to the end of a bolt, though thicker and with rounded edges worked through the filler.
that will provide the most advantage to gettin it 'restored'
damage is something that sticks out, a repair with carefull paint match can easily be invisible.
my bike has dents in the tank, but no creases, so they don't jump out at you so I leave them, if they were like yours, (especially where mine are) I'd fix it, or have it fixed.
real question is, is it eye catching, do you run into friends who say "I saw you on the freeway today riding your new bike, man what happened to the tank?" or do you have friends who know the bike and see it a lot, and one day ask "wow is that a dent?"
first fix it, second, let it go.
