What is the difference for MAGICKCORE_QUANTUM_DEPTH(16, 32)

====== Quote =============================
MAGICKCORE_QUANTUM_DEPTH (default 16)
Specify the depth of the pixel component depth (8, 16, or 32). A value of 8 uses half the memory than 16 and may run 30% faster, but provides 256 times less color resolution than a value of 16. We recommend a quantum depth of 16 because 16-bit images are becoming more prevalent on the Internet.

There are three choice for build parameter MAGICKCORE_QUANTUM_DEPTH, 8, 16 or 32. Also there are comparison between 8 and 16. But what is the difference between 16 and 32? Can value 32 get better image quality upon converting?

Thanks!
