There have been several recess SCOTUS appointments. Eisenhower made three. As you point out, the Senate can reject the appointments, and has done so. Unsuccessful recess appointments to United States federal courts.

That article is about recess appointments to the federal or lower courts as they are known.

FROM THE ARTICLE: John Rutledge, appointed by George Washington was the first recess appointment to be rejected by the Senate, and the only recess appointee to the Supreme Court of the United States to be rejected.

The article doesn’t speak to any SCOTUS recess appointments that were ultimately successful.
