According to various Internet comments, .PNG SHOULD NOT BE DONE WITH CACHE For example: https://www.dareboost.com/ You should not gzip/deflate PNG images!

Is Lighthouse Report wrong ?

@ggmggm I see where https://www.dareboost.com/ says you shouldn't gzip png images, but I don't see anything suggesting you shouldn't cache png images. I think Lighthouse is correct on this matter.
