I hate to be pessimistic about this acid wash fix but I seriously doubt you will find the post acid wash finish acceptable. The disparity in color and the size of the blotched area is quite substantial.
In any event, should the PB want to see what it looks like with water in it, I would be sure they refill the pool with no more than a few feet of water, if that, as this will be sufficient to gauge if the acid wash eliminated the blotch (ie do not get talked into a complete fill of the pool).
