Just checked and it appears that jest/no-identical-title doesn't report an error when specifying the title using backticks (even when not using string interpolation).
Error:
describe('an odd case where identical titles are not reported', () => {
it('this works as expected', () => {
// ...test code here
});
it('this works as expected', () => {
// ...test code here
});
});
Not reported:

it(`this does not work as expected`, () => {
// ...test code here
});
it(`this does not work as expected`, () => {
// ...test code here
