Speaking about the in-game fictional scenario:
The JREF has reasons for reserving the right to publicize the results of challenges, including some that would apply if a challenge were successful. As a non-profit organization, the JREF has fiduciary responsibility to spend its funds in ways that are legal for such an organization. Essentially, if they pay out a million dollars, they must prove that they had to by the terms of the challenge contract. Publicizing not only the results of the test, but the full raw data including video records, would help them do that.
One likely event in the aftermath, then, is a lot of skeptics, magicians, and even fake psychics poring over every frame of the video to see if they could spot a trick. Speculative theories of "how it was done" would proliferate, and if any such theory could manage to be complete and consistent with the evidence, it would likely become a popular explanation for "how the JREF was duped." Of course, preventing any such theory from being possible is the goal of the test design, but it's hard to say what people would come up with after the fact. More likely, there would be a few competing and variously flawed theories, each contradicting the known facts in different ways (and covering up those contradictions by asserting that some of the data or evidence was faked, one or more of the skeptics were in on it, and so forth).
If a strong theory arises, there would be calls to repeat the test with additional controls in place, and possibly, sponsors coming forth to offer to pay for such tests. So, your psychic character could have additional income from that, although that would probably be minor compared to things like appearance fees to be on talk shows and the like.
Now, the real million-dollar question in this scenario is, how successful at such public demonstrations would a real psychic have to be, before some "goat staring" types in the government got involved. I know the evil gubmint whisking fledgeling psychics (especially minors!) off to secret high-security laboratories is a horrible cliché but there are actually some pretty good reasons why governments would be concerned about psi powers if they had good evidence that they existed. You'd pretty much need a reason why the intelligence agencies wouldn't be doing that, if they don't, in the game. For instance, a high-level government official who blocks such plans because he's a mole for the Chinese and wants China to get a lead on psi research.
Wiser psychics might play it a little cooler than that, keeping their public exhibitions on the level of "better than Uri Geller but still probably just really good tricks," figuring that most of the public will believe it's real anyhow and will line their pockets accordingly, while at the same time they wouldn't be frightening the powers that be too much.
