Price is a simple term which doesn't imply any structural marketing approach, it is just a simple transaction price.
Price point references sales volume - profit maximization strategy, and is appropriate when consciously aware of structural marketing factors.
Price point(s) are literally a point inflecting complex demand curve, which is situated at price which most efficiently captures demand volume.
If you look at graph at Wiki entry for it: https://en.wikipedia.org/wiki/Price_point
...You can see prices 1/2 way between A/B/C would only capture ~1/4 additional volume)
In re: PS5 price point discussions, structural impact on sales volume is overtly the context of discussion which is why term is used there.
Many informed reviews will use the term because understanding context of product within business strategy is part of 'meta' of the product.
(as we can understand microtransactions have economic logic driving their existence, they aren't just some random minigame for own sake)
I'm sure people can use it not quite accurately at all times, but it's generally used when consciously considering mass market pricing structure.
From a consumer perspective, price point is the same thing as price. So unless you're in a company strategy meeting, just say price. Otherwise you just sound like you want to appear smarter than you are.
