I don’t think it’s an event, I mean, none of the other rips seem to be related to the game, I think the SiIva team is celebrating the fact that we have more than one rip of Yellow, now that the game, and therefore the soundtrack, is finally out
For the Wiki there needs to be at least 4 rips for this to be considerated a event (unless the event is advertised by the channel itself aforehead, like the RIAMU YUMEMI NUMBER ONE SUPER IDOL TAKEOVER from 2022 which only had 3 rips but was "officialy" aknowledged as an event so the Wiki counts it). There were only 3 rips uploaded in the release date in question and the rest were uploaded the next day (note that this channel uses the Pacific Timezone as basis for this); so in conclusion, no, it doesn't counts as an event.
