Copper gutters

I have a job this week and have been reading about the horrors of SH + Copper… I’m not even sure if these are made of copper and looking to get some input… I know it’s hard to tell but I don’t have a better picture… If these are indeed copper, I plan on just keeping them wet, and maybe do the high areas near the gutter with a lower strength mix as well, since the building isn’t even that bad to begin with. Thanks
