Sadly a lot of supermarket bread is made using the Chorleywood process https://en.wikipedia.org/wiki/Chorleywood_bread_process https://en.wikipedia.org/wiki/Chorleywood_bread_process Smaller bakeries will have a wider range of bread types and in my area the local shop will sell polish style rye breads and Caribbean breads (usually sweeter and denser) The dark bread you have in your picture is available in London but can be a bit tricky to find (I would expect larger supermarkets to stock it) It's also not too difficult to get middle eastern flat breads with a little bit of searching.
