They called it UHD for a reason, because neither 4k or 2160p were accurate. Though we won't know until we actually have UHD Blurays in hand to compare with Blurays of the same films on both UHD and HD tv's/pj's, on paper at least a 2k film still has significant chance of looking much better on UHDBD than on regular BD.
I think there are 3 basic scenarios.
A)First, lets say you have a 1080p set and don't intend to upgrade anytime soon. Should you buy UHD discs?
1) you could get them for futureproofing if you think you may get a UHD set in the future. So far, they all come with bonus regular Blurays you can watch right now and UHD BD's are, at least initially, priced reasonably, so this is not a crazy idea.
2) If you buy a UHD player, you can't get the 2160p resolution or HDR or 10bit or Wide Color. Mostly. The trick here is that until we get actual players to test, we don't yet know exactly how the players will downscale (the best I've been able to gather is that all UHD discs
WILL play, but it will be downscaled, obviously). They may only allow 8bit/4:2:0/rec709 output, we don't know yet. There are some 1080p sets that accept 10bit if it can be repackaged as deep color by the UHD player (unconfirmed) and many that accept wider color (WCG) if the player does not force remapping to rec709 (unconfirmed) and some sets that will accept and display 4:4:4 chroma. UHD BD is 4:2:0 2160p which can be downscaled to 4:4:4 1080p, making it better than the 4:2:0 chroma on your current regular Bluray. Not all 1080p sets can accept and display 4:4:4 but some do. My projector does, as well as accept WCG. My hope is that they will allow 10bit/4:4:4/rec2020 output. We'll see. (Bonus: some 1080p projectors accept a 2160p UHD signal and may use that to make a better picture, like JVC's recent eshift projectors. So if you have one of those, and the disc does not force downscaling, you may get even better image quality. This may also give you incentive to buy a slightly used one in the future instead of buying a brand new $$$ 4k projector)
3) Even if the above does not apply, there is still the matter of UHD BD's higher bitrate and much better h265 encoding. This will give you more detail than regular Bluray. If you have a 70"+ display or a pj, you will want this, you should be able to notice this from a proper seating distance, especially if you have the regular Bluray to compare.
B) you've got an older "4ktv" that does not have HDCP2.2
1)we don't yet know what form of downscaling may be forced if you don't have recent HDCP. All discs will play (based on my reading of the Samsung UHD player manual), but if the studio sets a flag, it will force downscaling, but downscaling is not mandatory; so if the studio is not a jerk then you may be able to get full resolution from the disc. So for those discs that don't force downscaling, you'll get 2160p, WCG, 10bit (not many of those early "4ktv" sets were 10bit though, none had HDR), and the higher detail brought by higher bitrate and better encoding (h264 is over a decade old after all).
2)
About those 2k mastered films. See, if it's 2k, that means it has to be downscaled to be put on your regular Bluray. Then you have to upscale it to 2160p. Is that really the best way? Master->dowscaled->upscaled? Or would it be better to simply have the studio upscale the 2k to 2160p and you just display it? And your upscaler has to work in realtime, while the studio upscaler can take hours to render an upscale in the best quality possible. On resolution alone, UHD beats regular BD even for 2k films, in addition to the color, bitrate, etc, all making for, on paper at least, a measureably better picture. Of course, how much this difference is worth to you is a matter of personal preference. But if you are film enthusiast, why wouldn't you want the highest quality possible.
C) You have a recent UHD set with current HDCP and HDR.
1) why are you even questioning, you spent money on a high quality set, why wouldn't you get the content that actually makes full use of it?
2) if you're only concern is whether to buy films that are 2k upscales, see B-2 above.
On the subject of 2k films on UHD that you already own on regular BD, whether you choose to double dip is all depending on what its worth to you individually, but as I showed above, you will get at least some improvement no matter what. If you have a large set (>70"), you should be able to justify it for films you love. And if you have a UHD set, it should be a no-brainer for the films you love. Just depends on how much you love it.

I don't think dredd will have much improvement in uhd, since the dirty grimy look is what they intended on. But even then, I'd triple dip if they ever released dredd in uhd. Not likely though...

Well, Dredd actually did fairly well on disc sales, contrasted to poor theater sales. Many films have found profit on disc that bombed in theaters. UHD BD is another opportunity to make money, it all depends on if the bean counters think its worth it. I don't know if UHD BD will ever be like Bluray, but it took years for many films to get Bluray releases (or proper transfers), so if something like Dredd were to come to UHD BD, I wouldn't expect it for 2 to 3 years after the initial launch.
