This is the resolution of the YUV output of decoder, not the WebP input, and because of lack of post-processor, the output is not scaled, so can go up to 4K with WebP. Before WebP introduction, the maximum output resolution was FHD for all codecs. Now WebP allows up to 4K but FHD constraint remains for H264/VP8.
