Oki you said that there are some people who like the Film Grain, but by from what I have seen the general consensus is that it's bad, many even despise it, as seen here: https://discord.com/channels/303681520202285057/1179848372602023946
(alongside only negative mentions in ingame chats I have noticed over the past days)
And while you already added an option for it (#dev-wip message), it should be off by default, not enabled with 30% Intensity. Those few who really like it can enable it if they want to, but they are really a small minority that do not warrant changing the default graphics of the game from what it was 1 patch ago before Invasion introduction.
Else new players will join the game, think "wtf" is this film grain and maybe oversee the option to disable it.
