Just one pass of NR in PS then clean - not only sky but the whole image. The blue areas are in lower midtone level and noise is there; it proves the luminance NR in SPP is not so efficient and can even worsens.

One thing that SPP has no CA reduction, you can see it at all contrasty pixel level in the whole image. PS through ACR helps a lot in this department with CA reduction defringe feature.

And we should know that the NR algorithm now is very much smarter, it attacks only noise in the unwanted areas and enhances the highlights details.
