Why do you advise OLED to entrance tier builds?

I have 7800x3d and 4080, got this at the end of 2023.
Even with this build OLED is little too much, like 70-90% the price of the build. Monitors were always like 10-20% of the PC+monitor combo.
People on reddit calling me retard for having LG 27GP850-B for my setup.
