I also have "out of memory"-problem when using the LG WebOS to streaming TV channels. I have no problems when I use Chromecast. According to other reports of this problem, the weaknes has existed for a while, and it seems to come from LG's WebOS. I use a LG OLED55C8PLA. - Has LG decided to fix this problem, or is it an intentional weaknes, as sugested by some users?
