You can still “buy” albums digitally from Apple, and they are lossless, as they have been for almost-ever. The caveat being that you need a device capable of decoding ALAC files.
They have allowed you to rip your own music to lossless for more than 15 years, but I only just found out that when using iTunes Match, they cheat and only store a high-resolution but lossy version on their service.
Thanks!
