From what I’ve read, you want to make sure that the setting is spelled FILMMAKER MODE (in all caps) with a (TM) symbol, since that means that the body who popularized the setting has approved whatever the manufacturer does when you turn that on (so if there’s a setting called “Cinephile Mode” that could mean anything).
With that being said, I’ve definitely seen TVs that just don’t have FILMMAKER MODE or have it, but it doesn’t seem to apply to content from sources like Chromecast. The situation is far from easy to get a handle on.

Typically “Game” mode, on TVs, turns off post processing, to avoid the extra frames of lag it causes.
That doesn't necessarily mean it looks good or is tuned well, just that it has lower latency.
