YouTube's compression reduces the image quality quite a bit. Details are lost. Details are most certainly not gained.
Vantablack is supposed to absorb so much light that there should be no details visible. An area of vantablack should appear flat and featureless.

There are features visible in the darkness. I can see the left eye and brow ridge. There should be no light reflecting off the object in this promotional image, unless the lights used in the photo shoot are so intense that everything else in the image is blown out and pure white.

If I had money to invest, I wouldn't.
