P: Cannot turn off max compatibility programmatically in LrExportSettings

[martins26997302]

Version: 14.0.1

Platform and OS Version: Windows 11 Pro 23H2

When exporting an HDR image from a plugin, one cannot turn off the maximum compatibility setting.  This results in overly large files that are not yet widely processed correctly.

The following creates a minimal (?) plugin that reproduces the problem.

Expected: two exports are created, one with maximum compatibility off ("normal" HDR render) and one with maximum compatibility on (SDR + gainmap(?) render).

Actual: two identical files are rendered.

Info.lua:

return {
  LrSdkVersion = 14.0,

  -- 13.0: HDR settings
  LrSdkMinimumVersion = 13.0, -- minimum SDK version required by this plug-in
  LrToolkitIdentifier = "name.stolle.martin.max_compat_repro",
  LrPluginName = LOC "$$$/PluginName=Max Compat Repro Plugin",

  -- Add the menu item to the Library menu.
  LrLibraryMenuItems = {
    {
      title = LOC "$$$/CreateNew=Trigger",
      file = "Trigger.lua",
    },
  },

  VERSION = { major=1, minor=1, revision=0, build=200000, },
}

Trigger.lua:

local function trigger(functionContext)
  LrDialogs.attachErrorDialogToFunctionContext(functionContext)
  local catalog = LrApplication.activeCatalog()
  local photo = catalog:getTargetPhoto()

  if photo:getDevelopSettings()["HDREditMode"] == null then
    LrDialogs.message( "Photo not HDR", "Please select an HDR photo.", "warn")
  end

  tempDir = os.tmpname()
  LrFileUtils.createDirectory(tempDir)

  end
