Below are some images manually and automatically inserted into the blog using the wordpress media button. Some urls are correctly rewritten and others are not.
Manually inserted anigif from staging url. Since the URL is not controlled by production it properly appears (AWS plugin leaves it alone)

Manually insert regular gif from production. This is a static gif hosted on production. It is properly rewritten by AWS plugin

Manually inserted anigif from production. The AWS plugin will -not- properly rewrite this url

Media library insert static gif from prod. This is properly rewritten by AWS plugin.

Media library insert of anigif from prod. This is another anigif hosted on prod. AWS plugin does NOT properly rewrite this url so no image is displayed.
