I'm not trying to give you a hard time at all.
IPS describes one part of the electrical control equation in a complex electrochemical system.
When there was only one manufacturer and one version, it was enough to say IPS and that told the whole story.
Today there are a bunch of variations on the IPS control theme and they range from, eh ok, to, OMGZ amazing.
My phone has an OMGZ amazing IPS display so I know what's possible and what's to love.
It was nothing personal - I just have a thing against marketing departments not telling the whole story and turning an engineering identification into a buzzword - because then you and I can't know if we're talking about apples or oranges. I hate that and it's all I was about, as I hope my earlier reply to Clementine_3 bears out.
Cool?
