Some report that after experiencing a shift in their absolute pitch, all music sounds wrong. Some of them adapted somehow (it’s unclear to me how much development of relative abilities was involved) and others report not having noticed that their absolute pitch has shifted. Some report that only after they’ve lost their absolute pitch completely, they were able to develop certain relative pitch abilities.
Overall, people’s reported experiences in the comments vary a lot. I wouldn’t draw strong conclusions from them. In any case, I find it fascinating to read about these perceptions.
Rick Beato has a video about people losing their absolute pitch with age (it seems to happen to everyone eventually). There are a lot of anecdata by people who have experienced this both in the video and in the comments.
