I am not sure if this is new because when I search for videos, I use YouTube directly. But in Google Video search, Google will label YouTube channel landing pages with a play button and without a timestamp because the link takes you to the channel and not to a specific video.

Again, the reason this has that icon with a multiple video tab like label is because Google is trying to communicate that this is taking you to the Lucid Motors channel.

In the case below, which is how I found it, from Saad AK on Twitter – it takes you to the Ferrari YouTube channel.
