Crushed blacks means you're losing detail that the director/creator intended. Try manipulating your contrast and see if there is detail in the black spaces on screen that you're missing at your current settings. If so, then yup, crushed blacks.
A lot of people just think a very contrast-y image looks better - and stores sell this them way so they pop more - but loss of detail is the risk. Pro-tip: the properly adjusted image will always look a bit more washed out if you're used to the crushed blacks, but you just gotta accommodate to it, especially as you have an OLED with true blacks.
