The most recent ones I did were some Moon Knight collections, I ended up with each image file being 1248x1920 resolution. Does anyone have a CBZ backup they could check for the resulting resolution?

Moon Knight is a moot point since that's Disney/Marvel and has DRM.
There's a file size limit for JPG so I'm attaching azw3, azw6 and cbz samples of the same page in a zip file.
On an iPad Pro 12.9" (2732x2048), the difference in quality between the azw3 and cbz is especially noticeable. The compression artifacts on the azw3 version is very obvious on the large iPad.
The azw3 image was extracted using KindleUnpack so there should be no additional quality loss due to recompression. The azw6 image was extracted using a python script I found in these forums.
For what it's worth, the total size of the image repacked CBZ from Monstress #1 (source comic) are as follows:
15.02 MB Kindle azw3
66.72 MB Kindle azw6
123.82 MB Comixology cbz
