When I use RGBA colors inside a Jupyter Notebook, I obtain an unexpected result:

import pyvista as pv
import numpy as np

sphere = pv.Sphere()
scalars = np.ones((sphere.GetNumberOfPoints(), 4)) * 255.0
scalars = scalars.astype('ubyte')

p = pv.Plotter()
p.add_mesh(sphere, rgba=True, scalars=scalars)
p.show()

When I run this script natively, I get the right result of course:
