The information sent to the render engine has not gotten any feedback on the displacement.
The only workaround would be to use the Displacer Deformer. (Not the same, not as detailed, without extra effort.)
My workaround would be to use a Shader Effector with the displacement information. Note the that the Min/Max needs to agree with the settings.
• Intensity (Centered) -100/+100
• Intensity 0/+100
• Same with the Height (100%) and dimension must agree.
Since I have no file from you here, this is perhaps just a guess.
All the best
