I cannot recreate exactly your effect, but I noticed the following: if I 
convert to rgb I lose some of the sparkle, too, but that depends on the rgb 
profile I use. By default (stupid default, our bad), the Adobe RGB profile is 
selected when you convert to rgb. Much better results can be had with the 
lcms internal sRGB profile. (This is logical, since Adobe RGB is a pretty bad 
profile, for fun & kicks, create a white image and then switch to Adobe RGB 
as your display profile.)
