It's funny that you mention co-op and lidl.. neither of them actually have "bread fresh baked on premises including stuff like ancient grain sourdough" [0].
kwhitefoot is correct and the vast majority of bread in the UK is not what you think it is.
The bread in these two stores is mostly baked in a factory and then delivered to the store where it may be heated for a golden crust (at most). The ancient grain sourdough is (likely) just mostly wheat bread [1].
In my personal experience, I was always suspicious of the "fresh sourdough bread" at Tesco. It was far too soft to be real sourdough bread and now I think it was a straight-up lie- sorry just a marketing label.
