You may be right but it wasn’t jarring at all so I didn’t notice.
It’s not jarring /to you/.
My first thought when seeing that font was that the same font used to appear in Hal’s “9000 series” prequel edits. (Given the G in “The Approaching Storm” or the Y in “Labyrinth of Evil”) but he has since replaced that font with the correct one in more recent versions.
