2D pieces versus 3D pieces (OTB?)

Sort:

I am happy with my chess.com game on a 2D board, but in OTB games i always miss chances and lose pieces witch would not happen in 2D. My question is: If i become premium member (Platinum), because i can play with 3D pieces, should that improve my OTB game?

Thanks for viewing,

P.S.: With losing pieces, that happens in deep calculation because i don't notice pieces far away (edges)!

So basically i'm asking: Is playing with 3D Pieces in Live Chess the same as OTB / Tournament?
