Moments ago, I took a photo of my charging Watch using the Mono filter of the native Camera app on my iPhone 7. I did not turn on my old MacBook, but I did login to the iCloud website via Safari (in desktop mode) on my iPhone and saw the Mono colored pic I took of my Watch. I'm going to assume that since I have iCloud Photo Library enabled on all of my Apple devices, that Mono colored pic will display as such on them all. Having said that, how you "load them on" your Mac?
