More light output is not = more dynamic range unless the minimum light output stays the same.

A 400nit tv with 0.4nit blacks has the same range as a 100nit tv with 0.1nit blacks. it just displays the same image 4x (2 f/stops) brighter. Like putting a transparency on an illuminator and increasing the brightness of the illuminator, the transparency's contrast (range) doesn't change. To display more range you need increased contrast (range) on the TV (like 1000:1 vs 800:1)
