2.15.3 above leads me to think if I've been cleared a visual approach from an IAP then we have to conduct the IAP missed approach, not a standard visual missed approach.
I'm really glad you pasted this section of the AIP because it was this very paragraph that has brought the question to mind.
Interesting that we should both come to a different conclusion.
In this scenario, if we're given an ILS approach we will brief performing the IAP missed approach regardless if we stay in IMC to the minima or are cleared visual in VMC conditions.
