Keep in mind that native contrast measurement is done either using full-screen white image/full-screen black image (AKA "full-on/full-off" contrast) OR full screen test image using rows of black/white squares (AKA ANSI contrast measurement, which mimics closer the 25% average brightness level of most video content).
Full-on/full-off contrast figure is always higher because it is measured using full white screen reading followed by reading of full black screen whereas ANSI is measured using test image that has rows of black/white squares and brightness emanating from white squares which will "contaminate" the reading of black squares, thus lowering overall contrast measurement.
I have seen test reports for some Samsung VA panels reaching almost 6.000:1 full-on/full-off native contrast (without local dimming) and Sony/Vizio sets not too far behind, whereas LG IPS panels struggle to get above 1.200:1 native contrast.
With FALD engaged, some LCD sets such as the Sony Z9D can reach contrast level higher than 200.000:1, at least according to a very reputable online A/V site that tested it.
