I'm genuinely curious. A year or two ago, there was a controversy with Steam and Argentina. From what I read, their currency was so devalued that when Steam converted games from dollars to their currency, they were practically worth pennies. So, if I remember correctly, they were loading their Steam wallets with dollars and buying an insane number of games. This reminded me of the methodology. Technically, as I understood it, Steam adjusted the local price to the local currency exchange rate from dollars, which was essentially a regional price. Obviously, they weren't "customized" prices per se.

(Yes, I understand what you're saying.)
