Hello MacSass,
If you want to use Lightroom's recommendation, there should be no issues with using ProPhoto with Portrait Professional. You should make sure that Portrait Professional's settings are set to "Use profile from picture" to ensure compatibility. We support LZW compression of tiff files, but whilst your tests indicate that ZIP compression works, we cannot verify that issues will not occur when using ZIP compression.
We hope this helps.
