I just did some data in Cerulean Cave, not a lot, but enough to see if there is any changes.
Here are my raw data:
All this amounts are exactly in the list of amount the formula predicts. So it doesn't seems there is any difference.
Let's look the average in data and in theory:
With this distribution of level, i am supposed to find in average 313,78 pokedollars per PKM, in my datas i just found 291,52 pokedollars in average. It's a little lower, but not significant.
You can notice i didn't find lv 60 pkm, it's a new bug, the first level in a level range doesn't spawn xD should be corrected soon.
In final, it seems the formula didn't change for money, you should find exactly the same than before in average. Even the opposite, before the update, the last level of PKM didn't spawn, now it's the first level, so in an area the pkm have higher level, you should find more money ;)
