What people use a byzantium screen for
Byzantium is dark enough that a byzantium screen gives off very little light — on an OLED or AMOLED phone the dim pixels also draw little power, which makes it a good always-on or bedside screen.
Purple and violet screens are a mainstay of RGB desk setups, gaming rooms and stream overlays, where a purple wash sets the mood without being as harsh as pure red or blue. Purple lights the red and blue sub-pixels together, so it also helps reveal a failing green sub-pixel.
As a test pattern, a dark byzantium field is best for spotting backlight bleed and IPS glow on an LCD, or stuck "always-on" pixels on an OLED.
