I also needed to check if read/write was enabled. I came up with the solution myself:

NOTE: Solution is in C#

 try
 {
     texture.GetPixel(0, 0);
 }
 catch(UnityException e)
 {
     if(e.Message.StartsWith("Texture '" + texture.name + "' is not readable"))
     {
         Debug.LogError("Please enable read/write on texture [" + texture.name + "]");
     }
 }

Hopefully this will help anyone else who needs a solution to this problem.

TextureImporter importer = AssetImporter.GetAtPath (path)as TextureImporter; importer.isReadable = true;

"path" is the texture path you wanna change.

The question says at runtime. And the AssetImporter is a UnityEditor class.
