Can ImageMagick work with 16 bits per channel? This would be very useful when doing gamma curve corrections. It looks like it can, I think.

Yep, it definitely can. Just make sure you use the
-depth 16operator somewhere before you save as PNG and your PNGs will end up with a larger file size due to having 16 bits per channel. -
This Color Basics ImageMagick article is very useful. In fact, it’s so useful that it even includes a link to the excellent Gamma error in picture scaling article on 4p8.com that I include below and follow up with discussion.
** Important! In ImageMagick versions before 6.7.5, there was a bug such that the meanings of RGB and sRGB were swapped.
