Even with massive screens in commercial cinemas, 2K resolution and 2000:1 contrast for digital cinema DLPs is considered "good enough" for most people.
The impressive thing is the size, and the cost / inch is great on projectors. Although TVs are catching up because of economy of scale. DLPs have if anything regressed since 1080p days and I personally don't consider the 4K chips to be actual upgrades. They are at most "side-grades", sacrificing half or even 75% of their native contrast to get simulated 4K is not a good tradeoff in my opinion.
When you can buy a 100 inch LCD TV for under the price of a JVC, then projectors are going to suffer big time because most people don't have walls that would even fit a screen much bigger than around 120 inch diagonal.
If the Op is into gaming, then the 1080p Optoma HD27HDR might be a good choice. It supports HDR and 4K input but doesn't try to render the 4K at all, it just downscales. I believe this is a good strategy since there are numerous benefits to UHD Blurays and streams besides resolution. Bit depth, bitrate, codec efficiency, HDR, WCG, all those things could in theory help a native 1080p projector deliver a stunning image.
LEDs might not be as bright as lamp projectors but they don't dim quickly, so I hope by next year we'll have more choices like that. We definitely will, and at least Optoma and Acer have gamer-friendly 120hz 1080p DLPs out now (or coming out soon), with ultra low input lag too, that should put all other projectors to shame in terms of gaming performance.
With RGB LEDs or lasers, and no physical colour wheel, a DLP manufacturer could even, in theory, implement variable refresh rates, which are practically impossible with physically rotating colour wheels. Then DLP starts to look better and better.
