If its this I would put a lot of pressure on the toe/heel on a coarse hone, which may result in a slight smile until you get even contact.
Additionally I've been known to wear the spine down also, What is the spine wear like without the tape, is it flat?
It doesn't look to drastic so shouldn't require a regrind. I would re grind though if once corrected you got fat bevels or excessive spine wear.
The bevel does look a tad big for my taste, it just means longer time on the stone.
