There was a problem hiding this comment.
I double checked: https://github.com/Qiskit/qiskit/blob/main/qiskit/circuit/library/standard_gates/u.py#L357-L375 and this is correct the angles were backwards in rust and we didn't catch it because the tests were using the same values for all the parameters.

Summary
Fixed #13118.
Details and comments
The matrix representation of
CUGatein Rust accidentally swapped two arguments (phiandlam). This didn't fail the tests, because there all parameters are set to the same value. The tests are therefore also updated to vary the parameters values within a gate.
