Can anyone confirm that there's no way to read video using VideoCapture without losing alpha?

Based on a previous question asked here, it looks to me like OpenCV discards the alpha channel when reading frames from video using VideoCapture. Is this correct? Is VideoCapture not capable of reading the alpha channel of a video? I just want to make sure so I'm not tempted to keep trying. I've tried messing around with the "channel" argument in VideoCapture::retrieve, without any success so far.

the "channel" argument in VideoCapture::retrieve is more for multi-head cameras (think kinect), not color channels
