   A good hint may be if the very first bootup screen - probably with a
black background - mentions anything related to Telus. If it does, there
probably is Telus-specific 'firmware' in the system partition(s) of the
device and a factory reset should bring the device back to the way you
got it, i.e. Samsung+Telus stuff (assuming that the "Telus phone-boutique
counter" personel did not do anything special to the device which *they*
got from *their* supplier).

I agree with Frank that there's enough variability that we can only list
the probable scenarios (which have already been listed, AFAICT).
My suggestion, along with agreeing with Frank that the OP might want to
very closely record (with a second camera perhaps) the on-screen messages.
That might catch the situation where the OP can then figure out if the
Telus software is always there, or if the SIM downloads it, or if the
Internet Wi-Fi/cellular data downloads that Telus carrier customizations.
Also, given we know the SIM card can be involved, I suggest the OP *remove*
the SIM card for the initial boots - and only place the SIM back in later.
Again, I'd set up a jig of some sort that films the on-screen messages as,
from experience, I can say some of them flash by in merely an instant.
In addition, I suggest for the first few minutes that the OP ensure there
is no Internet access (data or Wi-Fi) to the phone, and then, closely
monitor the on-screen messages when data is eventually enabled.
Good luck. Thanks for asking the question as I learned from the research.
Being purposefully helpful and kind hearted has advantages in knowledge.
