"Angled" is the wrong word, because it suggests an alignment similar to that used with the sCO seats and the IPTE set up is completely different.
Some of the UD seats are offset from the row in front due to the narrowing of the fuselage. This is particularly pronounced in row 13. The seat itself is not angled but your viewing angle towards the video screen (which is mounted over the row 14 footwells) is noticeably offset.
