zmokkie If manufacturer of your box modifies u-boot (in Android firmware) so that it can wake on IR remote and adds a correct IR code, then it works. For example, I have a few boxes where it works: WeTek Hub, Minix U1, Beelink GT1.
Most manufacturers enable only "fake" shutdown in Android (read: device is awake, only HDMI is turned off) so they don't need to modify u-boot (read: lazy).
