got the new iPhone 7, restored via iCloud from my iPhone 6 save, and all the photos I have are now low res. When I click on them, i get the loading icon in the bottom right corner and it downloads the high res. I have 'download and keep originals' selected in the photos and camera settings option, yet it doesn't appear to be doing that. I have 10 gb of photos on ICloud Photo Library, yet my phone is showing only about 1 gb. What gives?
