No visualizations of Y-PSNR are available because the MSU VQMT software requires image dimensions to be a multiple of 2 to generate them.
The following images are compressed by each codec to approximately the same PSNR.
In my opinion they are not all equal in subjective quality, however I leave it to the reader to make his/her own determinations.  DLI, 22764 Bytes (60:1), 34.98 Y-PSNR
 Kakadu JPEG2000, 50488 Bytes (27:1), 34.98 Y-PSNR
 Jasper JPEG2000, 49443 Bytes (28:1), 35.02 Y-PSNR
 HD Photo (WMP), 47883 Bytes (28:1), 35.13 Y-PSNR
 IJG JPEG, 58556 Bytes (23:1), 34.98 Y-PSNR
