It is quite easy to demonstrate the blooming effect on LED-backlit LCD TVs that come with the local dimming function. You'll need to switch to a video input with no active signal, then pay close attention to the onscreen display. There should be a strong "haloing" effect around the white text, logo or symbol. As explained in our article, this is due to backlighting leakage which unnecessarily illuminates the fringes of lit pixels.
