Bluntly put, if I install a high-tech digital EQ in my stereo system, mike my living room and measure the frequency response from every end of the room, and hammer the EQ so my phase and frequency responses are as flat as they can be, the whole music experience is gone.
Sure, from a mathematical, computational point of view, the response of my audio system is correct. But it's just those little quirks and oddities that give a sound system (player, amplifier, speakers) a specific colour, often to your taste. That's why you chose it in the first place.
Lighting fixtures and lasers are no different. Some lighting techies really don't like the gobos or colour wheels on a Robe spotlight and are lyrical about Martins, and the other way round, just as some people here don't want anything but 473nm, argon, or mixed gas for their blue or full colour projectors.
