Yeah so, I think the best thing you should do here is to simply investigate.
I'll give you one example which is somewhat related, but mostly just a fun fact.
Google Maps, at least in the UK, is usually based on street names. "Go to XYZ Street", in "50 metres turn right". And when Google was expanding to other countries, they used the same logic, and it works in most places. But they found that people just weren't using Google Maps there "for whatever reason". And the reason wasn't because India doesn't have street names and whatnot, they certainly do... So, what the UX team at Google did is they sent people to India, and just asked people for directions to random places. And they found that, people often used landmarks. They would say "So, go like 25 metres in that direction, when you see the statue, turn right, until you see the pink shop at corner, then turn left". Things like that.
And, they took that concept, of using "Landmarks" and incorporated into their UI design (see the images below). It's not that India didn't have street names & address, or they were just behind in the times, or something, it's simply that, even though they were given the same parameters, they just took a different approach. So, rather Googling trying to change Indians themselves, they just modified their design to work for them, and found that when they made that change, the market in India adopted Google Maps much easier.
So, moral of the story, ask someone from Lithuania: "which design looks better", not just your design vs the original, but other websites too, and try and figure out how they actually view the website. It's possible, that they are indeed just behind in the times / outdated or something, but it's also possible that it's something else.
