There's nothing that can be done except sourcing the original cd's or buy lossless if available. I know exactly the feeling -- you want one lossless archive and instead the arrogant google / apple / amazon SELL ONLY lossy dissing users who want premium quality .. How hard is it to provide an additional lossless compressed copy for these idiots in 2018 !? Yes 100% brainwashing and dumbing down of the population.
To be fair, the codecs and settings/bitrates used by Google, Apple and Amazon's online music stores are high enough quality that they should sound just like the original lossless source.
Think about it from the perspective of these companies; they have to store God knows how many albums on their servers to have available for people to purchase and download or stream on demand. What do you think they'll opt for? A lossy format with a more or less predictable file size? Or a lossless format which can be anywhere from pretty much zero (excluding container overhead, metadata, etc.) for digital silence, all the way up to the same size as the uncompressed original (for uniform white noise)?
Me personally, since these companies tend to sell music in high-quality lossy formats, I'm fine with them as long as I make sure not to encode them lossily again.
There is a bandcamp site that does lossless for some alternative artists.
It's funny you mention that; it isn't unusual for bandcamp to sell "lossless" music which almost certainly comes from a lossy source, though this usually isn't due to sheer malice, but simple ignorance; quite often, artists aren't aware that if an MP3 is converted to WAV or FLAC, the lossily discarded information won't come back.
