My results were much more modest (webp lossless filesizes were pretty unimpressive). Try if you don't get better compression with lossless jpeg 2000 or jpeg-XR (the former achieves better ratios). Make sure though that your software uses the reversible transform and yuv conversions. Jasper (also used in imagemagick) apparently fails to.
