Maybe you are referring to some of the sites that use Spotify's API, like https://musicstax.com/ or https://tunebat.com/? The problem is that these sites often display inaccurate data. Although I haven't delved deeply into the issue, at first glance, it seems that what they label as "loudness" corresponds to momentary or short-term loudness rather than integrated loudness.

It doesn't save them in the folder with the FLACs so I have to manually copy every log file from my Documents folder to the proper location.... Source: about 1 year ago

You can use this to check for artificially inflated bitrate/bitdepth, its fairly accurate, or fbits which can detect exactly how much of the bitdepth is being used. Source: almost 2 years ago

If you have Windows, the Lossless Audio Checker can tell you in about 2 seconds if a WAV or FLAC file has been upsampled/ upscaled/ transcoded. There is also a CLI version for Mac. Source: over 2 years ago

Losslessaudiochecker.com paired with spek.cc when in doubt gets the job done. Source: over 2 years ago

I read about it about a year ago and recently did some tests using https://losslessaudiochecker.com/ to see for myself. And indeed, some songs 320 or FLAC audio files I sourced from deezer were upscaled. Source: almost 3 years ago
