Paramount has no intention of revisiting the ST movies again, ever. The 2009 HD transfers, in all of their over-processed digitally-scrubbed glory, are "good enough."
Those Blu-Rays were released to coincide with the 2009 movie. If you wanted all ten movies spread across two thin-case sets, you were in luck. If you preferred the individual 2009-revised artwork with each film (DVD or Blu-Ray) you were stuck with even-numbered movies only. The only movie to get a remaster was The Wrath of Khan, which needed it. Every other transfer was scrubbed to conceal where remastering might have benefited the film.
So what did Paramount do to coincide with Into Darkness? Why, they finally released the odd-numbered ST movies (being the same 2009-authored discs, with trailers for the 2009 movie still on them) individually. You could finally have all ten movies separately packaged with their 2009-revised artwork if you wanted. All they "really" had to do was come with new 2009-style covers for the odd-numbered movies. So in essence, they held back on releasing the Blu-Rays of TMP, STIII, STV, GEN and INS separately in 2009 so they could have "something" to release whenever the Abrams sequel (Into Darkness) came out.
4k was already a thing when Beyond came out, so Paramount took ONE of the classic ST movies, the one that was the most popular, and remastered it in 4k... and then didn't release it in 4k. Since they were remastering it "anyway", they fixed the color-correction issues from their previous HD remaster and let the director rebuild his director's cut. For the first time, both versions of Meyer's film would co-exist on the same disc. Missed opportunities? They could have gone back and looked for old TV spots for the movie (like they did previously for the DVD special editions of The Motion Picture and The Final Frontier). Instead there's just the one Wrath of Khan trailer seen on every prior DVD release of the movie. There's also said to have been an alternate title sequence (on the initial batch of theatrical prints) that omitted the roman numeral from the title -- THIS would be a thing to see, especially since they were using seamless branching "anyway" to present the director's cut. But it didn't, it wouldn't, occur to them.
Later that same year, Paramount demonstrated they had not "actually" learned their lesson from their separate "retail exclusive" releases of Into Darkness by this time alienating consumers of Beyond in the same fashion. Who needs a director's commentary? Surely anyone "fanatic" enough to want all the extras would buy up all the retail exclusives, right? Right? (I didn't bother, my employer had already begun screwing me over by that point).
So what's left? Well, there's still that 4k remaster of The Wrath of Khan that has yet to see a 4k release. I predict they'll... wait for it... make a 4k disc to coincide with the release of the Chris-and-Chris movie. And that will be it. The other nine existing Blu-Rays will remain "good enough" where the remaining films are concerned.
(And if the Chris-and-Chris movie never happens? Then Paramount will release The Wrath of Khan in 4k for streaming only, to coincide with the Tarantino movie, on the grounds that it's already another two years later and "everyone knows" steaming is the future anyway.)
Studios in general are "just fine" with not having to press DVD or Blu-Ray discs for very much longer. And Star Trek isn't exactly seen to be in high demand. ENT was being prepped for high definition at the same time that Paramount didn't even consider producing Robert Wise' director's cut of The Motion Picture at anything higher than 480p. And they're fine letting that go rather than have to recreate the newer special effects in HD, let alone 4k.
And Star Trek V... I don't think even a box set would justify having to create new effects for it, even at SD quality.
