>> almost all monitors display 32-bit color anyway

Actually, I was surprised to find out that this is not the case.

"The inexpensive twisted nematic display is the most common consumer display type."

"Also, most TN panels represent colors using only 6 bits per RGB color, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available from graphics cards."
