No, it all depends on what you are using the 1D LUT for.
If you have it before the 3D you can use it as a 'shaper' LUT.
That is actually far more useful, as you can greatly increase the effective accuracy of the 3D LUT.
In such a workflow the 1D and 3D LUTs are treated as a single 'object'.
Having the 1D after the 3D means the two are separate objects. The 1D can be used to 'pre-calibrate' the display grey scale/gamma.
The 3D is then used for full calibration.
In a professional system (including displays) there should be 3 LUTs - 2x 1D, and a 3D, with the 3D LUT sandwiched between the 1D LUTs.
If you only have 1x 1D LUTs, it is far more useful to have it before the 3D LUT.
