How did you tell it was changed? I think you can check the device itself and get the model number to tell

Yes, but the point is that I don't trust the labels that came with the device, because they were not very well pasted and I found some information that was mentioning that the device was a T8E. I wanted to know if there is some way to check it digitally or even by some physical difference between the models

I don't really think it's easy to fake a label. But it can't be find on the device manager and anywhere.
