Displacement: different result with Cache Normals

[RotemS]

Hi

I was under the impression that 'Cache Normals' should only affect render times and memory usage.
In this case render times are improved, but results are also very slightly different. Is this normal? (no pun intended)

Please see attached images.

It's normal for the result to be different. It can be improved though.

Best regards,
