It is wrong to consider neoprene with a single compressibility coefficient it has two, one for the bubbles, and one for the elastomer.
The bubble portion should behave as an ideal gas and have a linear compression coefficient.
There is no reason to believe the elastomer compresses linearly.
Each portion of the material, bubble and elastomer, contribute to buoyancy independently of the other.
Thus even if the elastomer did behave in a linear manner you could still have an effective nonlinear change in buoyancy because each portion of the material changes buoyancy at a different rate and the sum can not be described by a single linear coefficient.
