LT3492, LT3496, & LT3597 Minimum LED Current?

Question

Hi All 
 
 Would anyone be able to tell me if LT3492, LT3496, & LT3597 have a minimum LED string current? 
 
 For example with: 
 
 LT3492 one of the plots only goes down to ~100mA, so would it be safe to assume minimum LED string current is ~100mA? 
 LT3597 one of the plots goes down to ~1mA, so would it be safe to assume minimum LED string current is ~1mA?

Cheers, Anton

Hi Anton, 
 Apologies for late response. LED current for these parts can be lower than the current you mentioned. This is a little complicated and there can be loss of accuracy at low end and it might not have been characterized.)
