ScreenToWorldPoint for WebGL build and Editor return different values

Hello everyone! I have a Game window with resolution 1280x720. Script, that translates screen corner coordinates to world and print it to console:

 var cam = Camera.main;
 Vector2 LeftBottom = cam.ScreenToWorldPoint(Vector3.zero);
 Vector2 RightTop = cam.ScreenToWorldPoint(new Vector3(Screen.width, Screen.height, 0));
 Debug.Log($"Left bottom: {LeftBottom}");
 Debug.Log($"Right top: {RightTop}");

Then, i check output in the editor and webgl build and its different! As i understand editor consider screen aspect ratio, but the webgl build not for some reason. So why this happens and how I can get values in webgl similar to editor?
