If I have the DRL's enabled in the cluster menu the DRL's are on, of course, during day light full bright, but then when the head lights come ON at dark (or I manually turn headlights ON) the DRL's go to much dimmed mode. They stay ON, but with much less intensity.
If you have the "Daytime Running Lights" in the "On" setting, then the lower LED strips on the bottom right & left will turn on during the day & at night - these are the two small light bars closest to the ground with a chrome housing.
Also, not to be rude, but you can just put the car to the settings you mentioned, and go see what it looks like outside.... lol

Even in the U.S. some E-class owners have cars that turn DRLs completely OFF when main lights come ON. Mine keeps them ON with main lights in both E and S550 but with much lowered power.
Front of the car looks better in dark with DRLs on but to keep them startling other road users in dark the intensity must be lowered.

But anyway when either both Locator Lighting and/or Exterior lighting switch-off delay in COMAND are ON: The headlights are ON (at night). DLR are ON too if enabled in Instrument Cluster menu.
I my case I had no headlights ON in these modes. A minor coding has fixed the issue.

google make some spyware that often sorts out the issue - until Merc engineers invent there own magic of unrelated words/combinations of words/abbreviations
Mercs using canbus fun can illuminate other bulbs as a stand in for a failed bulb... (aka substitution) I expect chopping and bodging looms will throw this in a tail spin
Cornering light substitution
Cornering light substitution fog lights (I guess means use fog lights instead)
Re-trigger time of headlight activation (this didn't translate well)
Replacement light function active (enabled)
