Muted Pictures in LR 4.3

I am using a macbook pro with  calibrated LCD.I am having an issue with LR4,when i edit the images in cs6 photoshop ,pictures are more contrasty and richer.Both are in the same colour space ProRGB,i have no soft proofing on ,on both applications and i am getting different colours.( I have also made a different profile v2 instead of v4,i have read that this might cause a problem).

Strange thing is that I right click>edit in photoshop,and the save the image with no adjustments and comes back to LR4 with rich colors and contrasty.

Can somebody explain why is this happening?
