This isn't correct. Dialnorm existed before the "Dialogue Intelligence" algorithm. If you were to use an LM100, you would just turn off "Dialogue Intelligence" to get the dialnorm of material without dialogue.

Dialnorm is just the averaged perceived loudness over the course of the program. Dolby later refined their measurement method with the "Dialogue Intelligence" algorithm, but every program, with dialogue or not, has a perceived loudness.

You can use Audioleak to find the A-weighted Leq. This will be your dialnorm.
