Are all LG G4 screens and frames compatible?

[AC Question]

My wife cracked the screen on her LG G4 LS991. I can find a few for the H810 or H815 and have asked a few online vendors and they have said that the screen and bezel are not compatible with the LS991, although some online stores advertise them as compatible. I don't want to fork out stupid money for something that won't work. Anyone have any ideas? Thanks

Looks like the 810 is but not the 815.
