> outperforms PNG, lossless WebP, lossless BPG, lossless JPEG2000, and lossless JPEG XR

PNG was not designed to be used for photograph-like images. The rest of those were not designed to be lossless formats, the lossless version is just a tacked-on afterthought.

Very unsurprising to find a codec that can beat those.

In my own tests, I found FLIF generally beats PNG (PNG Crush/Optipng both in brute-force mode) for comics (greyscale, majority white) as well, but by a less significant margin.

It's also worth noting that there aren't many other lossless formats, so it's still a valid comparison. I'm sure neither TIFF nor RAW outperform FLIF either.

That's not a valid comparison for TIFF. TIFF is a container which supports multiple compression algorithms. You could plug FLIF in as a compression algorithm and use it directly.

Alright, well against current commonly supported TIFF compression algorithms such as LZW, Packbits, and ZIP.
