Agreed. I used to be blown away by a game from a technical standpoint 2-3 times per console generation and at a similar clip on the PC side. Now we are getting GTA V and Skyrim re-released for the 10th time. Neither of those games were groundbreaking at the time (IMO) as they both were good but predictable progressions from their previous entries.
Playing DKC and seeing the detailed sprites, Mario 64 (and several others) ushering in 3D, the FMVs in FF VII, and the enemy AI in FEAR, these things felt like monumental leaps forward. Nowadays, the closest thing I can think of is something like Elden Ring or TotK which to me is just taking an existing good game (Dark Souls/BotW) and slapping a mechanic onto it (Open world/crafting). They are both excellent games, but neither compare to the leap forward of FF VII or Mario 64.
Maybe I’m just jaded by adulthood and have my rose tinted glasses on.
They did look better on CRTs. Modern displays will smooth things in a way the original developers didn’t intend. It’s less pronounced in the PS1/N64 era, but SNES/NES has some games that look noticeably worse without applying a filter.
