As someone who is red/green colour blind, I disagree that they are an incorrect choice.

Annoying at night yes. But wherever they are used I can finally make out the difference between an ok/nok status.

Ah, I’m red/green blind too but most blue leds in electronics don’t seem to have a status function beyond "on/off", they’re there just to look futuristic.

Yeah my phone charger has a super bright blue led in it. It's kept in a draw at night as the entire room lights up. I keep meaning to cut out the led.
