Keep the LED for a while since if you get the OLED, your LED won't look the same.
My bedroom Sony is very nice, but it doesn't hold a candle to the OLED. My plasma gets very close on non-HDR/Dolby vision content, but once you play an HDR movie on the OLED, the difference becomes very apparent. It's pretty cool.
The only down side is now I very much want a projector that has good HDR support. My best display is in the room with the second worst sound system.
