In case you come back.
From your screenshot: The Resolution in your screenshot is 923 x 606 Divide either into your 3848 x 2775 @300 ppi image size gives a scale factor of 4.169
Divide 300 by 4.169 = 72 This is the original setting for CRT computer monitors. These days it can be much higher, depends on monitor quality.
..."Preview" is just the name of the application that opens PDFs on a macbook... - Could be an issue there, there might be some embedded small image in the download. You can get the same in some image formats.
However, as mentioned before, you should still look at Scribus as the tool for generating the PDF. Amazon from their how-to seem to prefer a PDF x1a format. You can get one of those out of Scibus, but it is a steep learning curve.
