I have 2018 model with webOS 3.8 (55SK7900PLA). This will get updated as well, right? Currently only webOS 4 users are reporting back.

Got an update for my TV, BUT without this features, only bug fixes... I doubt webOS 3.8 will get them.

https://www.apple.com/apple-tv-app/devices mentioning only "LG SuperUHD TV – SK9, SK8 series (2018)".

Mine is SK7900 where K stands for 2018, but looks like there was miscommunication and not all 2018 models will get it.
