Scorpio is also more powerful, however it looks like they are trying to pull an Xbox 360 on microsoft and launch something good enough but earlier.

Neither Scorpio nor PS4 pro would actually do 4K gaming, they will however most likely will have no issues of doing true 1080p gaming at 60fps which is considerably better than either of the consoles can pull off as well as maybe a few 1st party / indie titles at 4K.

I don't actually think the UHD BluRay is going to be an issue, BluRay sales aren't exactly have been great in general and considering that UHD BluRay movies tend to cost about double I don't see the sales being that great. Streaming 4K however should be considerably more important as Netflix and the likes are getting more and more UHD content you would want your console to be able to catch up.
