According to the paper <https://arxiv.org/abs/1707.06278>, the "James Webb Space Telescope should be able to constrain the obliquities of nearby warm Jupiters to be small (if <=10degrees) or to directly measure them if significantly non-zero (>=30degrees) using the technique of eclipse mapping."

As of 2024 the axial tilt of 4 exoplanets have been measured with one of them VHS 1256 b having a Uranus like tilt of 90 degrees +- 25 degrees. <https://arxiv.org/abs/2410.02672>
