Most LCDs do not have low radiance, illuminance, whatever today's name
for backlight intensity setting is. And if you do it the hard way - in
the profile - then say goodbye to one of your 8 bits resolution;
change the color temperature from native, and you now have a 6 bit
profile. Time to dither :)

Yes, if you have controls that will dim your LCD to CRT luminance levels, and are willing to do so, you can get similar luminances from the two. But no, thats not what most people do.
