Is kimchi refrigerated in grocery store?

Have you ever noticed when browsing the grocery store aisles, whether or not kimchi, that beloved Korean fermented vegetable dish, is typically kept chilled? I'm curious to know if stores prioritize preserving its freshness and flavor by refrigerating it, or if they opt for shelf display to make it more accessible to shoppers. Do you think the decision to refrigerate or not might vary depending on the store's location, target audience, or perhaps even the type of kimchi being sold?
