I'm pretty sure they both should be v4 in order to make use of the perceptual Profile Connection Space.

Actually, the profile connection space has nothing to do with rendering the case of the sRGB Perceptual profile, the rendering intent is used in the receiving color space. So you can convert from a standard v2 ProPhoto RGB into the v4 sRGB perceptual profile and take advantage of te gamut compression of the perceptual rendering intent. I have it an use's useful for images with highly saturated red and blues.

Thanks for the info, Jeff. Good to know it works with v2 ProPhoto RGB.

I was thinking of this statement on the ICC's sRGB download page :

"The sRGB v4 ICC preference profile is a v4 replacement for commonly used v2 sRGB profiles. It gives better results in workflows that implement the ICC v4 specification. It is intended to be used in combination with other ICC v4 profiles."

I guess you don't have to use a v4 source profile, but potentially the results are better if you do?
