The 2050 and variants are usually a first time projector purchase. The aspect "most" people want to upgrade is black level, even if it's in 1080p.
To do that, the room has to be treated for reflections, which many people are unwilling or unable to do.
A projector with good black level in an untreated room is still an upgrade, but will be hampered by the wall reflections.
Regarding the other upgrades that a 4K HDR projector would bring:
The seating distance and/or screen have to be adequate in order for the viewer to see the increase.
Some faux 4K projectors only have ~4m pixels vs the ~8m that 4K should have.
The newer 4K DLP's have decreased contrast from the 1080p models (generally speaking), only two models exist that have a dynamic iris.
Some models have an pixel enhancer feature to increase sharpness/detail.
Even though the DMD chip or other component can produce a 4K image, the lenses also matter. For instance the HT3550 does not have great lenses, while the Epson 4/5/6xxx series have (better lenses). This reduces the difference between the faux 4K in 4m vs. 8m. Lenses for the same 4K DLP chip product can make a difference in sharpness, even variance in the same model.
Native 4K projectors are still expensive.
Just because a projector is 4K does not mean that the image will automatically be sharper, even with the caveats just mentioned. The source is also important.
In order of quality: video shot in 4K or higher (in 4K resolution)/video games (although there are some issues here with internal resolution), video shot in 2K (in 4K resolution), 1080p upscaled to 4K. In some models the 1080p version is sharper in 1080p resolution than when the projector upscales the 1080p (source).
HDR tone mapping:
Projectors can't reach the nits level that TV's can to display some of the brighter parts of the image.
There is no agreed standard between manufacturers, so everyone has their own interpretation of how HDR is supposed to look like.
If the HDR tone mapper is proficient, a HDR signal can look better than an SDR signal of the same resolution, even without WCG.
Expanded color gamut:
A filter is used to achieve higher color gamut. The filter can reduce light output by 50%, 40%, etc., depending on the model. Some people prefer the brightness over the WCG.
This feature is present is some older generation 4K projectors, which can exceed REC.709 without a filter. For instance the Epson 4xxx and 5xxx can achieve 85-89% of DCI P3 without the filter. REC.709 is ~70% of DCI P3.
Access to higher bandwidth content for streaming, 4K HDR of different types.
This can also be done with some players/boxes on an 1080p projector. HDR tone mapping can also be achieved via an external box like the Panasonic UB420/820/9000 (the last two support Dolby Vision, which I don't believe any projector supports), or madvr is using an HTPC with an 1080p projector.
Some models 4K models can achieve 120Hz in 1080p.

This projector (HT2050) is still state-of-the-art at the $500 price point. There's going to be a lot of regular HD content for years to come so a minimum requirement for me to upgrade it would be 1080pHD SDR performance that is in no way worse than what I already have. I haven't found any 4K projectors that can do this for less than 5 grand.
Any 4K projector path for me
- Must not have higher blacks
- Must not be louder
- Must not give less than 120 nits on a 1.0 gain 100" screen from 10 feet
- Must not have lower Rec 709 gamut coverage
- Must not take away 3D
when displaying regular 1080p SDR content.
Show me such a projector that belongs in the sub-3K section of the forum. Before we can talk about going forward with new technology we must establish we're not going backward in the old technology. It simply can't fail the 6 tests above or it's not an upgrade.
You mean must have higher blacks?
Projectors like that already exist, the Benq HT3550/5550 and Epson 5040UB(refurb or not) and 5050UB, Epson HC3800. The Optoma 4K lineup will have similar black levels to the HT2050, and the HT3550 and HC3800 slightly better.
Or used JVC.
3D is susceptible to ghosting on the Epsons, but there are plenty of users that claim it does not manifest.
LE: haven't done the number on the 120 nits part, but the HT3550/5550 are less bright than the HT2050.
