Dynamic range is not a precisely defined term for digital images - for example, if there is a single white pixel and a single black pixel somewhere in the image, then the dynamic range could be considered to cover 0 .. 100%.

Driving home this point, in the program Raw Therapee, "The Auto Levels button increases the brightness automatically while the percentage of the blown out area on the image does not reach the specified maximal clipping ratio set by Clip." (RT manual) I believe default Clip = 1 percent.
