From the complicated rules it looks to me like the Iowa story isn't going to be completely over anytime soon because
There's "redistribution" of the non-viable votes (below the 15% threshold) at the district conventions as well, to be held on April 25, 2020. So for example, Kobluchar who looks below 15% SDEs presently, but still winning some SDEs will send precinct delegates to these district conventions, but these will have to decide on that day (April 25) with whom they realign with. (see pages 25-27 in the rules)
A similar thing happens with the state-level (aka "at-large") delegates but on June 13, 2020. (pages 35-36).
(There are 27 district-level and 9 "at-large" delegates.)
So while SDEs are (or were) used to announced a/some winner(s), the actual delegates aren't fully decided based on the events (precinct caucuses) from February 3. Is this correct basically? I'm skeptical that I understood this correctly because I can find no media articles discussing the process beyond the precinct caucuses.
