If lab grown meat takes off there's no reason in principle for why cattle, chickens and pigs couldn't be replaced by say the blue whale, dodo and black rhino.
We might even find human meat at the supermarket. If all you need is a small cell culture to bootstrap most or all current ethical, conservation and disease concerns will go out the window.

Or completely novel creations.

Spoiler: Project Hail Mary brings up the concept briefly. Interesting novel otherwise, too.
I seem to recall a short story about a future in which you can order not just human meat but your own meat and even the meat of celebrities. It doesn't seem entirely implausible if you consider porn performers already lending their "likeness" to sex toys. You or I might find the idea revolting but there is absolutely a market for "eating your favorite celebrity". Alternatively in such a future one might make the ethical argument that "your own meat" is the only meat you can ethically consume because it does not require anyone else's consent (which might be coerced).
And I don't even think people are the primary market, but large industry; they're all about min/maxing, and don't care where the meat that goes into e.g. chicken nuggets or sausages comes from.
