I think you are confusing average game enthusiast or forum member to average gamer.
Lol...no average gamer is going to DF to find out TLOU runs 10 fps lower in one of the Pro modes etc...
Likely, a very basic, "Pro is a more powerful PS4 and goes along with a 4K TV" is about as deep as the 'average gamer' logic will go. All those bullet points is way more digging/reading than a large portion of the gaming audience will ever follow through on. It's not that average gamers are dumb, but choose to be uninformed because things like frame rate or native versus non native is not important to them.
And all that's assuming someone is informed enough to check all those bullet points and still not realize that the Xbox One S is a decent bit weaker than the PS4.
The bullet list seems to go more on the lines of:
-Most of the people that I know have one
-There's a game(s) that everyone is playing together on that system
At least in my opinion. I(and by extension my group of friends) have sold literally 20 PS4s purely for people to play Destiny, The Division and ESO with us even though a few of us own both. I can't get anyone to buy an Xbox because the majority are on PS4. Most circles of friends tend to have a bunch of people playing the same system from what I've seen.
There are always those who have other reasons besides playing with friends and in a certain ecosystem, but anyone who has ever read an IGN article or talked to a GameStop employee probably knows there's a power difference(and got opinions with a healthy dose of bias).
