should we careful the photo is the correct orginal one?

Recently, I changed the folder structure from {:%Y/} to {:%Y/%m}. When I used Duplicate Cleaner Pro to help me delete the duplicate photos (because some photos were already deleted from iCloud), I found out there were still a bunch of photos in the yearly folders. However, Duplicate Cleaner didn't recognize them because they were the same photos but with different MD5 checksums. I checked every single picture to find out why.

In the end, I discovered that some of them were damaged; there were some "color blocks" in parts of the photos or screen tearing.

Additionally, some large videos also failed to play because their sizes were only half of what they should have been.

so,my point is how can we avoid or how can we check the photo is excatly the same as icloud?
