The program, 2020 doesn't matter. If you mean they'd be more interested because they're watching byu on TV and not others, I don't think it does that much. It's still byu. They still need to win. They still need to produce NFL draft picks. They're still not P5.
It would help a little, but not much. It's not like byu wasn't "visible" before this. They still played on national TV constantly. Let's not exaggerate it.
