How to apply texture imported at runtime for the skybox panoramic shader?

My problem is the single longitudinal line appearing on the skybox.
The way to fix this in Unity Editor is to disable Generate Mip Maps option in the texture import setting.

But how to fix it on the texture imported at runtime?

I have tried to set

Texture2D.requestedMipmapLevel = 0;

, but that did not work for me.

 

I have managed to fix this.
I am importing this texture using www class, as www. texture.
Then I create a new texture with no mipmaps and copy pixels to it.

Code (CSharp):

1.         Texture2D skyTexture = new Texture2D(www.texture.width, www.texture.height, TextureFormat.RGB24, false);
2.  
3.         Color[] cols = www.texture.GetPixels(0, 0, www.texture.width, www.texture.height);
4.         skyTexture.SetPixels(cols);
5.  
6.         skyTexture.Apply();

 

In Unity 2019.1, this also works (I'm loading the texture from a local file, so I'm not doing anything with WWW):

Code (CSharp):

1. Texture2D texture = new Texture2D(2, 2, TextureFormat.RGB24, false);
2.  
3. try {
4.     if (File.Exists(path)) {
5.         byte[] fileData = File.ReadAllBytes(path);
6.         texture.LoadImage(fileData);
7.     } else {
8.         Debug.LogError($"There is no file at: '{path}'");
9.     }
10. } catch (Exception exc) {
11.     Debug.LogException(exc);
12. }
13.
