The Boing ball is a long-standing Amiga icon; IIRC a lot of the early promotional photos of the system sported a badge with it instead of the rainbow checkmark.
(This is from dusty memories of being the spoilt kid who owned the third Amiga sold in New Orleans. I no longer have any of those old issues of Commodore/Run/Ahoy/Compute's Gazette/Amigaworld that these would have shown up in.)
The rainbow checkmark was one of the rebranding initiatives after the assimilation by Commodore. It was a nod to the five colour rainbow stripes next to the company logo on the C64/Vic 20 case and on all peripherals, monitors and drives included. The logo on the C64 packaging also was a full rainbow gradient, but in the case of the Amiga it was a reminder of the 4096 colour palette.
