Worth the jump from mini-LED QLED to OLED?

Currently rocking a 2020 TCL R635 and love it. Have always wanted an OLED but couldn’t justify the price. I can comfortably afford one now but not sure it’s worth the jump, or if I should wait another year or two.

Looking at a 65 inch B5 for ~$900 after tax and a 65 inch C5 for $1250 after tax. Is the C5 worth it or would the B5 be enough since it’s my first OLED?

I’m pretty sure it’ll be worth it but could use input from those with experience. It’ll mostly be for movies in a dark room and occasional gaming
