I never said I couldn't tell the difference between my corrected vision and the vision pro. But it's probably close to as clear as my uncorrected vision, which is how I experience life the majority of time. In a very real way, it is lifelike. My reaction to the cover coming off is "oh, I don't have my glasses on" not "oh, I'm looking at a screen". In no world would I have the same reaction to the passthrough on any other VR headset I own.
The latency, lack of screen door, minimization of warping artifacts, and yes, even the resolution, are at a place where someone who doesn't have the privilege of 24/7 perfect vision could easily mistake it at first glance. There's lots of places to improve (mostly the blur when moving your head), but we're at the point where "not literally indistinguishable" is the point of contention.
Also, keep in mind "lifelike" has never even meant "literally undisguisable" in the first place. People have been using it to describe graphics since the PS1, so I think it's fair to use to describe something that looks more like life than the majority of even present-day "realistic" 3D games.
