I really like V'ger's interior

[Shat Happens]

When Spock goes exploring, he enters the next chamber through a hole and visits V'ger's 3-dimensional memory.

When the Enterprise goes through the same hole, it travels into an entirely different environment.

It serves to show how alien and advanced, multi-dimensional V'ger is

Unless it has a teleporter... or ironically, elapsed time since they didn't want to re-show the same effects. Or it's just a goofy editing choice.

I've seen this movie hundreds of times. When Spock penetrates V'ger's orifice in his thruster suit he speculates that he is passing through a gigantic imaging chamber therefore everything he sees is an illusion. Later when V'ger opens her orifice to let the Enterprise in they are shown a different illusion. Of course that's just my interpretation based on the premise that Spock's speculations are always 100% accurate, I'd love to hear some differing opinions.

I’ve always assumed the imaging system is just off when the Enterprise is taken through…

I figured that the extra spiky-tunnel added in the director's edition is what the "holodeck" Spock saw earlier look like when it's turned off (which is supported by a new shot in the 4K version where you can see the spiky tunnel fading away in front of him right after he gets past the iris).

Well thank you.

V'Ger's interior is a giant holodeck.

I just wish TMP had the sequence where both Kirk & Spock explore V'ger's interior—still photos from that before the reshoots look pretty cool.
