In fact, taking the existing 1280x960 images, running them through waifu2x (resulting in 2560x1920) with medium and/or high noise reduction, and then downscaling to 1920x1440 via lanczos3 results in an incredibly similar image - medium noise reduction has more detail while high noise reduction has less, yet even on high there's a couple minor areas where the new 1920x1440 mobile images seem to not be as "noise reduced".Īlso there's still the tell-tale sign of chroma subsampling whereby waifu2x-ing the 2004 800圆00 lossless images still gives better chroma resolution. However, there seems to be some fine details that get lost, almost like some sort of noise reduction was used. They're almost certainly upscales, but from a higher quality (but not higher resolution) source than the 1280x960 lossy WebP images we have been using.
