75”+ Samsung QLED is your best bet.
They nearly match OLED for blacks at the top end of the range and have better brightness and a complete lack of image retention.
Projector won’t give anywhere near the same image quality / brightness / HDR / ease of use in comparison.
OLED is overrated, have some banding on my 65” B7 that I didn’t have on my KS8000, quite a bit of image retention that appears on menus etc after 30 seconds or so (which is just annoying) and the actual tv is slower to turn on / operate than the Samsung was. Also it’s nowhere near as bright which means daylight viewing is not as good.
