The filter you are using only stops jpeg compression. This does not prevent quality loss when resizing an image. Manually you would apply a sharpen filter afterwards to regain some crispyness in the image. WordPress doesn’t do that. However, WP does have the WP_Image_Editor class for image manipulation.
