Question about calibration #1

Hi, thank you for the app it seems to be working well but I have question about calibration.
I noticed that the command $ eyetechlsl stream starts streaming data immediately without calibration. Is this correct?
I can run the calibration procedure of quicklink seperately using an .exe file, and then start the stream with eyetechlsl app.
I tested this and the sample data also return a True value for left_eye_calibrated for example, does this ensure accurately calibrated ET data? Thanks
