Pretty much. But depends on who you ask.
VRPGs started as an attempt to convert TTRPGs to computers. One of the defining things in TTRPGs is playing the world in which you can try anything - which doesn't mean it will succeed - but you can try it. That is actual non-linearity, not the open world part. That automatically breaks any fixed structure, which means that, if your DM/GM is not some "failed novelist" who pushes you down "my way, or highway" railroad track, your story can take quite a bit of turns.
That said, that's extremely hard to do in VRPGs...nigh impossible actually, given that you can't code everything players can come up with - AKA, there is no DM/GM to improvise on the fly, and to pull strings behind the curtains. Sure, you can make world that is fully system based and drop players into it and let them do whatever they want to do, and that would actually be much more similar to how TTRPG began, where DM/GM is more of a impartial referee that "runs the world", but games that are trying that (like Kenshi to a degree, which is great game for what it does) tend to suffer from that same lack of actual DM/GM.
In early 80s, TSR, company behind D&D, started to push for that prewritten linear story driven approach with Dragonlance (they could sell more books that way)...I'm not sure how much certain VRPG designers from that era were influenced by it, but subsequently there is definitely a lot of RPGs that are made like that. Which makes sense from budget perspective, given it's way, way easier to make such game. Luckily, there where designers that kept to original ideas of playing the world, instead of playing the story, so there's plenty of games that tried non-linearity (with various degrees of success).
With recent advancement in AI NPCs (Ubisoft's prototype of AI NPC is a great example of what is to come), AI procedurally generated imagery and even early attempts at making fully-fledged AI DMs, I don't think we'll wait for too long to actually see the first VRPG that actually gives (to some extent) freedoms of TTRPGs.
