So I Googled "CFB Playoff $2 Billion", none of the articles that came up said anything about splitting that evenly among 71 P5 schools or conferences the way it's been done with the existing model. The two articles below made specific mention that it's unknown how revenue would be split in the new model.
You're assuming that the new model will distribute the massive new revenue equally when there doesn't seem to be any indicators out there that that will be the case.
A new College Football Playoff with triple the number of teams involved could bring in three times as much money to the conferences and schools that share the wealth.

"How revenue would be distributed in a new model was not part of the
detailed proposal the CFP unveiled Thursday. The 12-team model is at least three steps away from final approval from the university presidents and chancellors who oversee the CFP."
It's unknown how revenue from an expanded CFP would be divided, so it's hard to estimate how much more money conferences - and schools - would get.
