Short anecdote: There's a donut shop in my town that sold vegan and regular donuts in adjacent but separate displays. In some instances, the donuts on the regular side were also vegan, identical in every way save for the label. They found that they sold far better without the word "vegan" attached to them, and eventually stopped labelling them altogether, providing a side-menu to help vegans identify which are which.
Point being, perception is surprisingly important when it comes to taste.

I'd argue that it really doesn't matter how similar to meat these products get, if they're still seen as "fake". Even if delicious, people tend to gravitate towards "real". But hey, maybe they've found a market that wants this that I'm just not seeing.
