So the pressure has improved to 15 now, which suggests its working itself out. Many folk's clean pressure is in that range. You can certainly finish the slam with that filtration level.
I won't tell you not to tinker if you want to tinker, but I'm a fan of the adage "first do no harm"
What is the update on the slam? For right now, I believe that's the focus. The slam will also lighten the organic stain areas together with sunlight. In a perfect world, I'd like to see you finish the slam completely before you fool with the pipes or try to vac again. That would also give you time to pick up the vac basket I linked you to in order to prevent any further clogging.
Next time you pst a pic, show the whole pool so we can compare day to day.
