2300 EUR in 2014 was ~3151 USD, as you say. At today's exchange rate, 3151 USD is approximately 2710 EUR. In January 2017, 3151 USD was approximately 2993 EUR.

Apple will give themselves a cushion to prevent undesirable pricing discrepancies (or the need for frequent price adjustments) if the U.S. dollar strengthens against the euro, so a product that they sell at 3150 USD after taxes in the United States would reasonably be in the ballpark of 2800-2900 EUR in Europe given exchange rates in the last year or two. This is rather close to the parent post's stated price even without adjusting for inflation.
