They can get better but it's a battle if you want a high enough frame rate and resolution.
I used to think 360 and PS3 graphics were mind-blowing (I grew up with a GameCube and Wii mostly) but a lot of them look like garbage compared to Series X, PS5, and Gaming PCs.
To my eyes, Xbox One and PS4 are clear improvements over their predecessors. Series X (don't have one, but I know it looks similar to PS5 in performance) and PS5? It's mainly load speeds and more 60 FPS and dynamic resolution support. I don't think I've even seen one PS5 game that looks that much better than the best-looking PS4 games running on a PS4 Pro.
