I've found a nice example. Compare the lawn, the part above the arc (especially on the right) and the uppermost window on the two 0.17 MB images. There are parts that look like the JPEG2000 encoder inserted big blotches where details should be. JPEG2000 seems to be better at large, gentle gradients and strong discontinuities between solid colored regions. https://www.imagepdf.com/images/jpeg2000.jpg https://www.imagepdf.com/images/jpeg2000.jpg
