The main reasons I’ve seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don’t have anything to do with the taste of meat.
Since lab-grown meat doesn’t cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
Given that the point of lab grown meat is to stand in for butchered meat, I think it’s fair to assume they’ll target the same taste/texture. Honestly, what’s even the point of the discussion without that premise baked in?
