What differentiate a 2100 rated player and a 2300 rated player (lichess rating). Is it the opening theory, endgame tactics or what?

That can differ a lot, depending which rating you mean and which two players you take. The only general rule is that when you have multiple games of players with rating difference of 200, the expected mean score is 75-76% for higher rated.

Usually when there is a 200 point difference, the higher rated player is stronger in all areas of the game.

It can be a lot of things. No one answer. Tactics and calculation, as well as better positional understanding are the main reason. Another reason is resigning too fast - people who resign immediately when they're losing or much worse can easily sacrifice 200 rating points, especially in rapid or faster.

Here’s another way to think about it:

Let’s say I hypothesize that a 2300-rated player is better than a 2100-rated player in the endgame.

Are the games played in similar conditions? Do they have a similar pool of opponents? Do both players experience more or less the same level of mental fatigue? Do both players use the same opening and middlegame strategies? After answering these and other questions with a definite 'yes,' only then can I start measuring endgame skill.
