There are four 'colors' in the RGBA module. Red, White Green and Amber. Each of these colors are 3w. That means that the only way to get a real 12W color would be to turn all of those four colors on, which would result in a whiteish orange.
Two colors (purple, for example) would be 6w. A single color (red) would only have a brightness of 3w.
Hope that explains it
R= Red
G = Green
B= Blue
A= Amber
It is a trade off of brightness. You would be getting basically 3 watts of color from each diode but you can always mix say two diodes at maximum (255) and have a 6 watt bright color or you can put them all up to maximum and get a weird silver blueish white.
To answer your question, yes RGBA is sacrificing brightness for the unlimited color options... basically millions of color options/
