It appears to be so!
I have another update on my experience of buying hi-res music from Qobuz. I decided to run tests on the files that I purchased and discovered that Lossless Audio Checker (
https://losslessaudiochecker.com/) flags one of the albums as 'upsampled.' I contacted Qobuz. They have a procedure to raise a complaint with the record labels. I had to provide the log from the software (that, in this case, doesn't explain much) and the hash5 keys from the files to ensure that I am testing the files that they provided.
So far, I can't get a refund, because:
"Please note. There are no refunds on purchased music in any circumstance. We strongly recommend listing to the music in the streaming service before making your purchase if you doubt you will be happy with your purchase. The record labels do not allow for returns. There are no exceptions to this rule. I am very sorry."
This makes sense because they have no way to enforce that I will not keep the files if I get my money back. That is another problem with the music industry; we get punished because of those who engage in piracy.
