ColorSync utility does nothing to adjust HDMI color; in Catalina

From reading the guide, it seems that ColorSync has exactly and only one adjustable control that applies to the appearance of my display; that control being for "white point". Everything else seems to be a fancy display of information with no way for the user to actually do anything about or with the information.

I have a Samsung television, and I want to watch a video. My MacBook Pro is hooked up via HDMI. The colors are absolutely horrible, lots of violet, some green, almost no blue at all. The television's "picture" set-up shows options for "sharpness," "color," and "tint," but these are not adjustable when HDMI is plugged in. Presumably, I should be adjusting the HDMI source. But the source is my MacBook, where I control practically nothing. I can create a new "profile", but so what, when I can't adjust the values in the profile? In fact, I can't even adjust a profile that I just created; the ColorSync utility just keeps creating more, useless profiles.

As far as I can tell, ColorSync is not intended to be capable of doing anything useful for my purpose. It is a fancy bit of uselessness.

I am running the new Catalina OS version. I have seen other complaints about ColorSync in relation to Catalina.
