Imagined Life hasn't been published yet, but it's coming out later this year and it sounds really interesting.
Obviously, cetaceans would need to evolve hands in order to manipulate tools. And as comkiller mentions, you need the ability to work with fire to smelt metals and fire ceramics. So they can be as sapient as they like in the ocean, but there's going to be an upper limit on their tech unless they move onto the land.
Humans started out as a terrestrial mammal, then evolved into an arboreal mammal, then we came down from the trees. Sapient cetaceans would likely go a similar way: starting as terrestrial mammals, then evolving into aquatic mammals, then evolving into terrestrial mammals.
If the sapient cetaceans remain in the water, they can still engage in husbandry and selective breeding. For an example of an underwater sapient's technology, see James Cambias' A Darkling Sea.
Interestingly, I think there's a section in the book I Contain Multitudes about this https://www.amazon.com/Contain-Multitudes-Microbes-Within-Grander/dp/0062368591
Found it! It's by Alec Gillis!
Eyespots continue to confuse and scare therapods today.
Many moths and butterflies have eyespots to deter birds, and we even use eyespots on bird repellent devices.
