Conflicting information: does the Hikari 535 Shinkansen exist?

I wish to travel by Shinkansen from Tokyo to Kyoto in the evening of 24 February, as late as possible, keeping in mind that I will have a Japan Rail Pass and thus cannot use Nozomi trains.

The Hyperdia website is often recommended, and it shows that there is the Hikari 535 train leaving Tokyo at 20:33. However, Hikari 535 does not appear on the timetable on the operator’s website.

Who is correct?
