For reasons a lot of responders have mentioned, the question of value is a lot more complicated than how the OP put it.
However, I will add that the NIL is hollowing out the talent pool in the late 1st and second round. There may not really be significant differences in talent in that range of the draft. It used to be the case that some more talented high school players who didn't have a great freshman year in college might jump to the draft just to start the clock. That was a way for teams to get better talent later in the draft, if they had a good relationship with the agent and the player liked the situation.
It's not just domestic talent but international as well. You see foreign guys choosing to play college ball as a precursor to the NBA, whereas in the past they'd be in a Euro league. Teams that were good at scouting international players could sometimes get a better talent later in the draft than expected.
Now, eventually all these players will have to come out, since you can't play college ball forever. In a few years, things should normalize. The better players might still come out early and lose money in the short term, just to start the FA clock. However, for the time being it may be that players' values will more closely coincide with where they are drafted and there won't be as many unexpected gems in the late first/second round. The new rules that allow a player to declare and then talk to teams before deciding whether to return to college also might discourage talented but raw prospects to come out too early.
