Though the following does not clear the problem (at least for four
functions), it seems that the issue is about what arguments are passed
to *ColorFunction* when there is _exactly_ four functions to be drawn.
The following plots with five and six functions to be plotted,
respectively, work as expected.
SphericalPlot3D[{2, 4, 8, 16, 32}, {\[Theta], 0, Pi}, {\[Phi], 0,
3 Pi/2}, ImageSize -> 400]
SphericalPlot3D[{Sin[\[Theta]], 2 Sin[\[Theta]], 4 Sin[\[Theta]],
8 Sin[\[Theta]], 16 Sin[\[Theta]], 24 Sin[\[Theta]]}, {\[Theta], 0,
Pi}, {\[Phi], 0, 3 Pi/2}, ImageSize -> 400]
