Ultra realistic lures are intended to catch anglers.
One of my favorite presentations is the frog. I have ultra realistic ones and some that are just black or white. Look at the bottom of the frog (the part the fish sees) it’s not ultra realistic.
Like @MickD said, it’s about getting that reaction out of them whether it be sight, sound, feel, etc. Heck I saw a YouTube video of a guy using a Lego Chubacka with a hook and he caught a smallmouth. 😁
