If you haven't done so, I would add a spacer or two to lenghten the LOP to see if that lowers your POI.
You stated that the gun shoots high and right which would seem to indicate you need to move the "rear sight",your eye, lower and to the left.
A longer LOP should lower the POI as your cheek will contact the stock further to the rear, thus lowering youe eye.
If the gun continues to shoot to the right try putting a layer or two of moleskin on the left side of the stock to move your eye to the left.
Did the gunfitter have you shoot the gun or did he simply takes some measurements? I believe most good fitters would have you shoot both for POI and at clay targets before finializing the fit.
