Are graphics really evolving??

I've noticed that peak game graphics were like..9 years ago at 2016 and 2014,Assassin's creed unity,metal gear solid v,COD advanced warfare,2018 too was top,rdr2 was an absolute nightmare for your gpu,the amount of detail is unmatched,God of war,marvels spiderman (the first part in 2018),the graphics were absolutely thriving,but now..i don't know I feel like they're still the same lol,I can't see a difference or any kind of improvement,it's only so slight,a nine year old game still has crisp graphics and details
