But seriously, the first question should be: are the bits the same bits? Streaming services usually only have one version of an album, and usually they are recent (remasters). Most people with a lot of CD’s had them for decades. Fact is that between then and now, there may have been half a dozen rereleases, and none of them are the same. Just check https://dr.loudness-war.info/
, and see how the dynamic range changed throughout the years. Usually the older releases have the better DR.
Now if you rip your CD’s properly and use a streamer to play the same files, they shouldn’t sound any different.
And if the streaming service has the same master as your CD, I would also not expect any difference, especially when using a lossless service.
Also, read up on how to do a proper listening test. Just a casual listen is not good enough. You’ll need to have some basic controls in place to remove your own biases.
