Need an app to compare 2 images, is there one?

Question

Images

I will describe the application, then it will immediately be clear what is needed:
1) I make a layout according to which the manufacturer must produce packaging (just bw text and pictograms), send it to the manufacturer in PDF
2) The manufacturer uploads this to his software, on which the machines print the packaging, The software converts it to its own format and saves the picture. Sometimes the manufacturer changes something in the layout.
3) after that, the manufacturer sends me a picture of how it will look like for him (it should be exactly the same), I check with my eyes and confirm or indicate that something is missing or incorrectly placed.
The manufacturer's designers may occasionally remove important text or icons, or change blocks without notice.
It is impossible to find out why they did it, for what purpose and how to avoid it in the future - this is Asia, where production at any level sins like this and it is impossible to extract information from them, “so everything is fine with them”, just follow and point out jambs.
Of course, sometimes you can't keep up. I would like to automate this process by using some kind of image differer - upload your own picture and a screenshot-cut from the one sent by the Manufacturer (usually this is sent in a huge canvas with different pictures).
I've seen online and neoline image diffs, but they all can't ignore aspect ratio or white margins on the sides and either refuse to work or end up showing a hodgepodge of two nearly identical images, just because of a slight aspect ratio mismatch
But you need something like "read the pictures from left to right, we see the same black spots of certain shapes (letters and pictograms) in one and the other image in approximately the same places, move on. But here there is no spot, but here there is, we mark with red point".
Is there something similar? Paid or free doesn't matter.
Or is there some other way to solve the problem, "machine learning" there or something like that?
Thanks in advance!
