Sony made this clear in their very first unveil if people were watching. Digital Foundry made this clear. There was videos and videos posted like every day.
It was posted in the PS4 Pro Faq on the Sony Blog. The problem was Sony was the donkey of the day because people were more overly concerned about the lack of a 4K bluray drive and then not being able to actually see much differences through a youtube stream of HQ games made folks at home see the Pro in a not so positive light.
There was a thread on it here. DF made videos/discussed it. The reason why it seems like shyt wasn't made clear was everybody was so quick to troll/act concerned about the shyt that they ended up derailing good intentioned threads like this one.

People rather talk about other shyt rather than read what's posted.
