I might not totally understand what your data looks like, so appologes in advance if I don’t quite answer your question correctly.
So it sounds like you have used the Python Calculator to create a point field that describes how each point moves. I assume that means you have an x,y,z vector that describes how each point moves. You say you can see that in the spreadsheet. You should also be able to color by that vector.
I’ve already guessed quite a bit on what you have so far. Assuming I’ve guessed correctly, I’m still not sure if these point vectors represent a displacement (i.e. how far to move each point) or a point coordinate (an absolute position on where to put each point).
If what you have are displacements, you can use the Warp By Vector 
filter. This filter will add your displacements to each point coordinate to put them in the position you want.
If what you have are absolute positions, you can use the Calculator 
filter. Just turn on the Coordinate Results checkbox and set the expression to be the vector field you created.
