Does the 5D3 LCD display blink indicating where there are blown highlights?

On my old 30D when I have the histogram displayed the smaller rendering of the LCD's JPEG will blink wherever there are blown highlights. I asked a stranger I met on the street who owns a 5D3 if this camera did this and he didn't know - he never bothered to look at the histogram!! He let me call up the histogram and I noticed the JPEG didn't indicate any blown highlights - even after I purposely overexposed a test shot.

I didn't have time to explore the Menu to see if this was an option to be turned on.
