 Hit @Mte90 - thanks for the bug report / feature request.

 Are you saying the `wp_editor_set_quality` filter
 (https://developer.wordpress.org/reference/hooks/wp_editor_set_quality/)
 is not applied during image sub-size generation?

 This filter is in `src/wp-includes/class-wp-image-editor.php` and I would
 have expected it to be applied because `set_quality` is called by each
 image editor during `load`.

 We still need to validate this filter works correctly when changing
 formats on upload (eg converting jpeg->webp).

 Currently that filter passes the image mime type, I wonder if there is
 more context data we could pass here (like image size) to address your
 idea of different compression levels?
