Power wash damage

I used  the Gemini restore kit on my six-year-old deck last spring and stained it with two black walnut. It weathered the winter well but I was going to put a maintenance coat on. My house painter tried to remove paint from the deck by power washing and removed not only the paint but some of the stain as well so it is splotchy in places.  Would it be sufficient to clean and brighten the deck and then put on the maintenance code or will this watching this still show? Well I have to strip the entire deck or power wash/strip? Including a pic. - not sure why it doesn’t show.
