The ACS1500SE driver from DTR says, "The drivers are delivered fully tested and preconfigured for 100mA output""
Additionally when DTR sells a module with diode and driver everything is correctly configured and tested before it goes out.
Is measuring the current at the input the same as what is at the driver output ?

No, Driver inefficiencies and the veriance in output voltage cannot be ignored, The drivers efficiency graph of the output voltage over the input will not worth gathering data for as it would take weeks since its SEPIC. TLDR no sorry, Not even for a rough estimation.
