Is there a skill difference between players of the same Elo but in different region/server? [closed]

My question is more statistics and data proof oriented than subjective. If possible I would like the answer to include some "cultural differences" inputs.

For example, I would assume that a diamond in the Korean server might be worth a challenger in the EUW server (based on the last LCS). My assumption is that those differences might also exist between other servers.

So is there a real skill difference? If yes, to what extent is this gap ? And the most important subquestion: why is there such differences?

For example, what would be the Elo of a platinum EUW in the NA server? Please don't answer with only the LCS results as a support. A way of answering this question would be for example by comparing the farming of players of same elo, in different server. But once again the farming only cannot properly answer the question because (for example, it's an assumption), Korean tend to be more aggressive and farm less than European who are more passive in the early phase of the game.

Quoting from wikipedia here (emphasis is my own):

The Elo rating system is a method for calculating the relative skill levels of players in competitor-versus-competitor games

Since a ELO system only rates the players relative to each other, different "player realms" will inevitably come up with different ELO ratings for the same theoretical skill level, because the whole player base itself factors into it. Additionally the league system as seen in League of Legends or Starcraft 2 are just "sugar coating" on top of the Elo system in the background. These were introduced to give players a more motivating experience when trying to rank up, because say fighting for a top ten place in your league is more motivating than being player #115846 and trying to rank up to somewhere between #115820 and #115830 in the grand scheme of the Elo system in the background.

Having said all that my answers to your questions would be:

Is there a skill difference? Yes, a more competitive environment will usually breed better players
How big is the gap? Unknown, until you throw all players into the same elo system and let them duke it out against each other. You could try and compare data points (a lot of them) and find a translation, but that highly depends on the complexity of the game and I'd rate League of Legends as very complex because it's, first and foremost, a team game.
Why? See quote from Wikipedia.

Is MMR based on Elo?

MMR is the acronym for "Match Making Rating". Basically, both Elo and MMR refer to a number that is supposed to reflect your relative skill level. The difference is simply that Elo results from the Elo-system calculation whereas MMR follows other calculations.

Is a higher or lower Elo better?

At low Elo, a skilled player will likely find it easy to rise in rank, while at high Elo, the quality of players improves. However, there is a certain range where skilled players can remain stuck regardless of their personal skill, which is referred to as Elo hell.
