galvalume Mess up during cleaning

So, 1 year old galvalume plus roof, oak trees over it made a mess of pollen and sap and dirt. I (homeowner) brooms the loose stuff off and hoses it down. But it is still filthy. Proceed to hose roof down again and clean it with strong mix 1/3 Krudd cutter / water, brush it down with a deck brush and then hose it off really well. It looks great- when on the roof. But on the ground, there are now dull, low sheen areas, kind of a haze mixed in with gloss areas, all glossy is how the entire roof looked when installed. I know I messed up with the cleaner being too strong (should pay more attention). I am thinking I stripped off the acrylic coat in some areas. Or at least made it soften and haze. Is the aged look of a bare galvalume, a “flat” sheen or glossy. Like I said, it looks great when looking perpendicular to the roof, when I am up on it, but spotty sheen changes when looking from the ground. Could I have messed up the substrate or is it most likely the acrylic and it will wear away and blend as a lower gloss sheen bare galvalume. If so, how long should it take for the remaining acrylic wear away and start to blend in. Thank you for your help

So this should slowly even out? Is the final aged product of bare galvalume glossy or matte looking, is it darker or lighter than when first installed?
Thanks
