Jiren was directly stated to be much stronger than Infinite Zamasu by Whis. And they merely questioned whether or not Jiren was stronger than Beerus, but even a super casual Jiren is already superior to Zamasu. Beerus was also able to sense Infinite Zamasu's energy, and merely considered him a pest. Where as, Goku and Jiren, Beerus was out right freaking out by their power due to the possibilities of them being stronger than him.

It wasn't until Goku reached his True UIM form and Jiren being 100% serious that they confirmed them to be above Beerus, but they were already confirmed stronger than Infinite Zamasu even at the first time Goku went Ultra Instinct Sign.
