Games written for the PlayStation exclusively get to take advantage of everything, but there is nothing to compare the release to.
Alternatively, if a game is release cross-platform, there’s little incentive to tune the performance past the benchmarks of comparable platforms. Why make the PlayStation game look better than Xbox if it involves rewriting engine layer stuff to take advantage of the hardware, for one platform only.
Basically all of the most interesting utilization of the hardware comes at the very end of the consoles lifecycle. It’s been like that for decades.
I’m intrigued.
For PS2, game consoles didn't become the centre of home computing; for PS3, programming against the GPU became the standard of doing real time graphics, not some exotic processor, plus that home entertaining moved on to take other forms (like watching YouTube on an iPad instead of having a media centre set up around the TV); for PS4, people didn't care if the console does social networking; PS5 has been practical, it's just the technology/approach ended up adopted by everyone, so it lost its novelty later on.
PS3s edge was generally seen as the DVD player.
That's why Sony went with Blue Ray in the PS4, hoping to capitalize on the next medium, too. While that bet didn't pay out, Xbox kinda self destructed, consequently making them the dominant player any way.
Finally:

PS5 did not have any novel approach that was consequently adopted by others. The only thing "novel" in the current generation is frame generation, and that was already being pushed for years by the time Sony jumped on that bandwagon.
The PS2 was the DVD console. The PS3 was the bluray console.
The PS4 and PS5 are also bluray consoles, however blurays are too slow now so they're just a medium for movies or to download the game from.
DualSense haptics are terrific, though the Switch kind of did them first with the Joy-Cons. I'd say haptics and adaptive triggers are two features that should become standard. Once you have them you never want to go back.
PS5's fast SSD was a bit of a game changer in terms of load time and texture streaming, and everyone except Nintendo has gone for fast m.2/nvme storage. PS5 also finally delivered the full remote play experience that PS3 and PS4 had teased but not completed. Original PS5 also had superior thermals vs. PS4 pro, while PS5 pro does solid 4K gaming while costing less than most game PCs (and is still quieter than PS4 pro.) Fast loading, solid remote play, solid 4K, low-ish noise are all things I don't want to give up in any console or game PC.
My favorite PS5 feature however is fast game updates (vs. PS4's interminable "copying" stage.) Switch and Switch 2 also seem to have fairly fast game updates, but slower flash storage.
Technically the PS4 supported 2.5" SATA or USB SSDs, but yeah PS5 is first gen that requires SSDs, and you cannot run PS5 games off USB anymore.
Console also partially had to be quirky dragsters because of Moore's Law - they had to be ahead of PC by years, because it had to be at least comparable to PC games at the end of lifecycle, not utterly obsolete.
But we've all moved on. IMO that is a good thing.
