With your current phone, go ahead and take two pictures - one normal, the other a picture of a picture of that thing
Now look at the two, and tell me you can't tell in a split second that one is a picture of a picture. There's a reason that it's a running joke on the internet that people need to learn to take real screenshot instead of taking a picture of the monitor - there's always annoying and obvious artifacts.
Except smart phone cameras will also improve - if anything, I'd say that over the last decade, the average smart phone camera has improved at a much faster rate than your average computer monitor.
Combine what I said with all the other Metadata that will be collected, and I'm quite skeptical that you could fool an actual professional with your scheme.
You could easily create a package that couples the authenticated device with a screen showing the faked images and bring that around. If there is a market for inauthentic images that appear authentic, people will easily bypass this technology.
With the resolution of modern phone cameras, don't you think you'd be able to literally see the pixels? Besides, phone cameras usually can't focus that close.
