As long as the pixel values in 8x8 (or 16x16) blocks are not changed, the blocks themselves can be rearranged, ...

You can remove some of that information, you can even amplify what is left, but you can't add any information that isn't already there. This is in contrast to a RAW file.

If you want your monitor to show how the colors will appear in a properly calibrated print, then you need to set the white point to D50 (full spectrum centered at 5,000K) and view the monitor in a glare free environment with D50 lighting at around 2,000 lux. If the lighting environment in which you are viewing the monitor is different than D50, you should ...
