Just completed the Nintendo List a bit more (probably still missing some)
On Sony's side, I just knew the 16 first titles, and out of those 5 do not belong to Sony, with one even being a multiplat title.
I bolded those which have been announced, but not yet released. Considering how long some games can take to make (just check the last Guardian, almost 10 years in the making) and the upcoming release of the PS5, I sorted them out because they may not release on PS4 (Concrete Genie and Dreams for instance should, Ghosts of Tsushima, not so sure)
Oh, and in italic, I noted those which are already dead or dying (meaning MMO titles which have been deactivated already or are scheduled to do so soon). I'd be pissed if I bought on of these, to be frank. They are valid entries though, just sad ones.
Half of the titles listed were actually third party titles, many of them small VR or f2p games. So that brings it down to Nintendo levels, which is much more realistic
Clearly you do not understand the concept of IP ownership, and you're inconsistent on top of it. Allow me to explain...
Wonderful 101 is a game developed by Platinum games, but is funded and owned by Nintendo. Hence it is on the list. Similarly games you crossed out citing their devs are indeed developed by a 3rd party developer but are funded and owned by Sony, yes even that multiplatform title you listed.
You can find the trademarks for other games on there as well and see who the IP belongs to, all those IP I listed are owned by Sony similar to most of the games that Nintendo puts out that are made by 3rd party devs be it Yoshi, or Kirby, or Smash Bros. or Pokemon.
Secondly you seemed to have inflated Nintendo's list there by adding some more titles I see, I went ahead and took a closer look at them as I couldn't have left those out if they actually qualified:
Captain Toad -Not a new IP, it's a spin off of a character from the Mario franchise.
Daemon X Machina- Not owned by Nintendo (http://nintendo.wikia.com/wiki/Nintendo_franchises)
Flip Wars- I can't even find this...
Devil's Third- Not owned by Nintendo
NES Remix- Not even gonna look it up, just by the name I can assume this is collection of old games and can't possibly be a new IP.
Pushmo- This has been around since Wii days...
Sing Party- Ok, So I did miss one...
Tokio Mirage Sessions- I have to question if you know what a New IP even means...
