Accessing ARKit Camra colors

Hey everyone,

I’m trying to get a Color array containing the raw camera pixel colors. But the textures in the UnityARVideo script don’t have the right types . I can’t just take a screenshot and get the colors from that, because there’s an 3D object in front of the area where I wan’t to get the color from.
Here is my code:

 Texture2D t = Camera.main.GetComponent<UnityEngine.XR.iOS.UnityARVideo> ().m_ClearMaterial.GetTexture ("_textureCbCr");

    void GetElementColorFromCenter (Texture2D _t)
    {
        Texture2D t = _t;
        Color[] colors = t.GetPixels ();
    }

See https://forum.unity.com/threads/how-to-access-arframe-image-in-unity-arkit.496372/. Not possible today as it’s a external texture
