I like to believe their tactics are so petty that Q team and real patriots don't stoop to that underhanded immature stuff. Plus, I think the whole "dial up the color saturation" and/or "warm up the temperature" thing backfires silently because most everyone would assume at the layman level that the colors are too hot (because everyone has watched video material with all sorts of color grading).
Furthermore I think these propaganda "masters" that actually DO pull these kind of tricks don't even get away with it in the first place because most people are too busy to call up a huge global cable network to get someone on the line and tell them to maybe desaturate or cool the color down a little bit.
The "hidden" Trump vote exists for all sorts of things besides just voting, and the DS literally has no barometer for these types of things, and thus have to just "hope" that everyone is as propagandized at a level equivalent to how clever they see themselves as being – which in the case of the DS is laughably and desperately stupid.
Basically the DS has lost before they even won because their "tricks" don't work the way they think they do, and instead of "tricking" they're just causing a boomer to think their TV needs a fixin'.
