Idea for reducing MD server bandwidth costs.

What about testing forcing Data Saver Mode as the default for a month and checking the bandwidth costs compared to previous?
And/or even experimenting with various compression ratios for AVIF (check out the wide support by browsers nowadays, https://caniuse.com/avif). It is VERY doable.
I did research on HEIF and JPEG-XL (.JXL file extension), but HEIF has that famous expensive licensing fee, and JXL isn't supported yet by anything but Apple browsers atm, therefore the AVIF suggestion.

If you wish, I could post various AVIF/HEIF tests that preserves more quality than JPEG at lower file sizes.
The idea is to keep all original file sizes, but change the Data Saver recompression software to use AVIF at a certain average percentage suitable for most users .
Reply back to me if you wish to see an example compression. (am currently setting up a script to generate 1-99% compression ratio files in a test folder)

Regarding file formats I already tried.
Is bandwidth actually a problem?

I imagine it's one part of the problem (more people upload more series to the server(s), plus bandwitdh, plus all the edge servers (caching, and other systems), plus redundant storage and backups, IT is ridiculously expensive unless you buy most hardware yourself and maintain it yourself.
MangaDex@Home would in theory offload only the bandwidth, but there is no recent "magic" innovative lossless compression for images than what exists, so we can't reduce the storage use without losing actual quality.
Redundancy takes more money, time and effort to get it right.
