Projectors are inherently low contrast devices. Even the best projectors offering contrast ranges of 130,000:1 are not nearly as good as those numbers imply. As soon as there is any ambient light in the room, contrast from a projector drops precipitously. This includes light reflecting off the walls in the room from the projected image, back onto the screen. With three-chip projectors, you have convergence issues to deal with, and most projectors put out a somewhat soft image. Single-chip projectors are the only ones that are really suited for computer use, for example. (but those have other problems)
The advantage of a projector is that you only need a relatively small unit for a very large image. (far larger than 92") There are motorized screens, and motorized shelves for them, which means that when you are not using the projector, it can be completely hidden away.
With a large 92" OLED display, you have to figure out how to get it inside your home and (presumably) mount it on the wall.
Now you have a massive black slab stuck on your wall at all times. Even with a fixed projection screen rather than a motorized one, you are left with a large white surface on the wall when it's not in use, which is far more acceptable.
And there's something to be said for the look of an emissive display compared to a reflective display. Even if the OLED produces a technically better image on all fronts, some people would still prefer to watch a projector - just like some people still prefer to use an e-ink reader rather than a tablet with a high DPI display.
Another advantage which projectors have is that you can use an anamorphic lens and project a natively 21:9 image. Unless manufacturers decide to make 21:9 OLED displays (and I really hope that they do) projectors are your only option for that.
Personally, I am interested in OLED at "television" sizes - the current 55" models are as large as I would ever want to have. Actually, that is already larger than I really want for a television. I would be more comfortable with something in the 40-50" range.
I am much more interested in projection at larger sizes than OLED, for the reasons mentioned above. I don't have a room which I can dedicate to being a "TV room" and cover one of the walls in this black slate. I can, however, have a smaller television in the room, and a projector/screen which drops down from the ceiling when I want to watch a film on a big screen.
Now make the OLED display transparent when it's off, or replace the motorized projection screen with a rollable OLED display, and I'll take one instead of a projector any day.
