I agree, the similarity to the Lyra, in terms of the soul of the instrument, is pretty minimal. They do both appeal to certain types of noisy ambient musicians and they probably have one well-known component in common, but that’s it.
There was one time on one of the videos when I thought “that does sound like something I did with the Lyra”… and then I remembered that particular piece of mine leaned heavily on Valhalla Delay 
If one wanted to list similarities and differences between the instruments, the differences column would be longer and more significant I think.
(One of them’s for communicating with whales, the other for doing witchcraft. Or I guess, alchemy.)
