If the book continues to climb I might investigate the process for removing the tape. I am guessing that is a CCS thing when it comes to that? There are no tears to the cover so I have no idea what purpose there is for the tape. .
If it is due to the weak staple... then what are you going to do? It's one of the better presenting copies in grade I guess.

I would leave it alone.
Looks great for the grade and would sell for a premium.
Thank you for taking the time to do this.
