i don't think it is misrepresentation, though. if you're new to the hobby, you might not expect it, but upon my first glance at the pic, you can see it's not actinic coloration.
i've noticed quite a few people heading towards the blue spectrum, lately, and i kind of like that color, myself. if there is a color of lighting that your corals excel with, plus they also look slammin under that color of light, why wouldn't you use it? because a couple people will think your pix are misrepresenting? i couldn't care less what everyone thinks, personally. when i get the cash up, i'll probably try to emulate that color with my T5's, as well. i think it looks great, without too much purple
