This was a year or two before COVID. I think the reason why supermarkets stay open through the night is that they use the night hours for restocking shelves and figure they might as well be open for business. For the big stores like Winco, I think they all went back to 24-hour when allowed to by the state government. During COVID, they didn't switch to shorter hours by choice.
