JPEG2000 can be more of a data container than an image format. While the downsides are many, there are a few upsides to JPEG2000. Greater bit depth is useful when storing DNs. More than three channels is useful when storing multi-spectral images. Internal tiling is useful when range reading specific parts of an image (obvs more useful when working with very large images). These specifically make JPEG2000 more useful than PNG when working in certain domains. Satellite imagery is one such domain.
