The Radion Pro will improve your coral colours due to the additional Actinic LED's, but the effect you described above, wont be eliminated.
The reason I say this is because of the very directional nature of LED lighting. The issue is that most of the light is being aimed straight down; with MH and T5's, the light goes pretty much in every direction.
With my T5's, I have very good amount of light in every direction. Even in the corners of my tank, I get at least 155 PAR.
With MH, even though it is a point source; there is a large amount of light ie 250w of it, and the reflector brings most of it towards the bottom, but most areas of the tank will be lit up much better than LED's.
