There is competition. The question is, is there serious competition?
The short answer, is not a whole lot of serious competition. There may be some high end Barcos, or Digital Projections, or Wolf projectors that can compete - with most costing a good bit more, if you can find the ones with native 4K resolution.
From a day to day practical standpoint, the true 4K competition right now is JVC's competing 3000 lumen flagship, which is pretty similarly priced. I'm still hoping that one day, JVC will ship me one for review, but no luck in well over a year in trying to obtain one.
I don't have the pricing on the Wolf equivalent to the top of the line JVC, but it's probably a good bit more money.
That JVC should have great black levels. After JVC though, nothing out there, to my knowledge, will come close in terms of black levels, certainly not the vast majority of 4K UHD DLP projectors out there (and far, far, less expensive). Of all the 4K UHD projectors I've seen to date (15+), only one has even had pretty good black levels (the Acer laser - VL7860), but it still won't come close to this Sony.
This Sony VW995ES is one of the very first projectors to be IMAX Enhanced. OK, we're all familiar with IMAX and the great images they put up in those IMAX theaters.
Welcome to your own IMAX theater! Wow is the operative term. Simply stated, so far I have obtained one IMAX enhanced 4K UHD disc: Journey to the South Pacific. Stunning colors. (Sadly the older Journey to Space that I like to photograph, is not IMAX Enhanced.) I have two more IMAX Enhanced discs on order. I can't wait.
Historically, I have found that Sonys, to me, tend to have the most natural color (not talking sharpness, rather color). Their excellent "right out of the box" color likely makes it simple to have dead on the money calibrated color.
I can't think of any projector, whether Epson, JVC, Optoma, etc. that can match the color this VW995ES projector puts on the screen. OK, that's a big statement, but a true one.
So, what should Sony's VPL-VW995ES fear from the competition? That's easy, almost nothing. The exception. This VW995ES may meet its challenge when we can buy a 110" or 125" OLED display.
That's fine with me, but don't expect to be able to buy OLED TVs in those sizes, for under $100K, for a couple, no, more likely, a few more years.
Because "size matters" tremendously when it comes to being immersed in the content - so that you can "suspend disbelief," I don't see a real threat to this native 4K projector, as a "best solution." for quite some time.
