Actually, all we see is an Oberth-class ship, the front part of a warp nacelle, and the aft part of a nacelle & pylon combo that could belong to a different design. Can't really say they were any clearly
Constitution-class ships in that scene.
If anything, the scene initially caused a brief moment of confirmation that Kirk and the gang were going to get the Excelsior
until the last moment.

That depends on if you accept the Okuda Chronology's dates, which has ST II-V happening over the course of 3 years (2285-87) when internal evidence from the movies show them taking place over the course of a few months at the most.
In Okuda's chronology, Star Treks II-III took place towards the very end of 2285 and then Star Trek IV took place three months later in early 2286. He then placed Star Trek V in 2287 after presumably a year-long shakedown cruise (or space trials) of the Enterprise
They also have TWOK 18 years after The Space Seed rather than 15 (and yes, I am aware of the reasons why; and no, they can't be 15 Ceti Alphan years, since Kirk independently confirms the 15 year time-frame)
But it can be a figurative or off-hand number given by both Kirk and Khan. Quite a few people in the real world do that when being precise isn't an issue (Spock might be the only one inclined to give an exact number--even down to the month and day perhaps).
I think you have to assume that ST5 takes place shortly after 4 on the basis of Scotty's, "Let's see what she's got, said the Captain, and then we found out, didn't we?" The totally-different bridge appearance aside, of course.
Truthfully, that's one reason why I can accept Okuda's idea that about a year passed between Star Treks IV and Star Trek V. To me, it's perfectly plausible that the new Enterprise
-A was in service for awhile, discovered numerous problems during that time (which would still validate Scotty's comment), and then returned to Earth to fix them.
