Using OLED directly in names works because OLED panels inherently have common features like blacks, contrast, and lack of blooming over other panel types. They can have other aspects added in (e.g. tandem OLED or the like) but by saying it's OLED you include these base things without needing a unique term.
Saying other panels are LCD tells you next to nothing as there are so many types which can be paired in so many ways which can all have completely different characteristics. It's not a conspiracy to hide the truth that people must only want OLED displays, it's an attempt to say something rather than nothing in the name of the monitor so you know what it actually is beyond "not an OLED".
If it were about trying to hide something the subhead wouldn't say mini-LED.
