Yeah.. you may see a little bit of light bleed if you are using the brighter of the two modes... if you use the darker one, you won't notice it unless you are in a totally dark room. The S7 and S8 have the advantage of being an AMOLED screen, on which light bleed is impossible since the only pixels that fire are the ones that are in use. G6 has an IPS LCD, so it fires up the whole screen... which is why the default is a very dim AOD mode and one that uses more power than the same mode on a phone with an AMOLED display.
