same, yet different

I have a lexical query that I’ve been trying to answer since shortly after starting cider photography but as yet have been unable to. I Tweeted about earlier today (and have had a few great suggestions) but again, no-one answered it outright so I’m putting it out there. If I can bring you guys closer to the problem, you may be able to bring me closer to the answer (and, actually, I reckon it’ll be really simple.)

Question: What word can I use to describe something as being both 'different' and 'exactly the same', simultaneously?

I'm looking a single word that summarise this phenomenon and as its a slightly tricky concept I’ll explain further using ‘cider culture’ to elucidate.

When I visit a country hoping to learn more about the ‘cider culture’ specific to that country, I have learned to look for two things: a) whats the same b) whats different. 

It may sound obvious, but being aware of these similarities/differences sets parameters to work within and anyone who knows anything about creativity knows us artist types need boundaries to work up to. I learned long ago that the space between those two places is where I want/need to point my camera because it helps me find what I’m looking for - the answers I want exist there.

Some aspects of cider culture are always the same (the use of the right apples to make it, the need of a press to obtain juice, the role of the cidermaker etc - the apples bit) yet, simultaneously, some things are entirely different (traditions unique to that region, legal regulation, natural advantages/disadvantages - the people bit) and I bet somewhere in the world there is a word that describes that phenomenon. This is something time after time everywhere I go looking at cider. It got me thinking that there must be other things that also have that nature about them, and so, somewhere - someone must have invented a word for it. It may have only be used once by an existential German linguistics professor but I’d like to start using it too! The closest suggestion so far has been oxymoron, but can that word be used to describe something outside of a linguistic context? i.e. ‘Cider culture is oxymoronic’.

I certainly don’t know, I even tried a few sketches to help me visualise the relationship between things to see if any ideas jump out (nothing yet.) All answers are welcome - please feel free to comment, share and make suggestions.
