I’ve had a mid-tier OLED tv the last few months. The colors and contrast look phenomenal to me. You get true black on OLED since each pixel is individually lit.
I watch a lot of horror films which will have many dimly lit or night time scenes. OLED makes those scenes much easier to see because of increased contrast between dark and light.
Not a protector per se, but I put this cover on my iPad that makes it feel like paper when you write on it. The cover magnetically attaches so I can put it on and take it off as needed.
