What is the logic behind selecting the "primary" release date?

When I make a call to api.themoviedb.org/3/movie/1433 (The Devil's Backbone), the api returns release_date: "2007-02-01", even though wikipedia, imdb, and my Criterion Blu-ray all say it was released in 2001. The moviedb page also shows a 2007 release year. I thought this might just be bad data, but then I hit api.themoviedb.org/3/movie/1433/release_dates and got this:

{
  "id": 1433,

    {

        }
      ]
    },

      ]
    },

        }
      ]
    },
    {
      "iso_3166_1": "GR",
      "release_dates": [
        {

        }
      ]
    },
    {
      "iso_3166_1": "US",
      "release_dates": [
        {
          "certification": "R",
          "iso_639_1": "",
          "note": "",
          "release_date": "2001-09-02T00:00:00.000Z",
          "type": 3
        }
      ]
    },
    {
      "iso_3166_1": "PT",
      "release_dates": [
        {
          "certification": "M/12",
          "iso_639_1": "es",
          "note": "",
          "release_date": "2002-11-22T00:00:00.000Z",
          "type": 3
        }
      ]
    },
    {
      "iso_3166_1": "RU",
      "release_dates": [
        {
          "certification": "",
          "iso_639_1": "ru",
          "release_date": "2007-02-01T00:00:00.000Z",
          "type": 2
        }
      ]
    }
  ]
}

Does the api select type 2 (limited theatrical release) ahead of type 3 (theatrical release) without considering the actual dates? I see the same pattern with Rear Window, which is apparently now a 2016 film thanks to a limited theatrical re-release in Chile. So now Plex tells me that The Devil's Backbone came out in 2007 and Rear Window in 2016.

To fix this problem when I use the api, I make an extra call to movie/:id/release_dates, doubling my api use. I use the following pseudocode to select the earliest theatrical release to use instead of the release date returned from the movie/:id call:

release_date = Infinity
for release in release_dates:
    if release.type in [2, 3] and release.release_date < release_date:
        release_date = release.release_date
return release_date

So how exactly does the api select the "primary" release date, and would it be possible to maybe reconsider that logic?
