Apple Music showing Hi-Res Lossless while listening on Airpods Pro 2

So i was listening to apple music and suddenly saw the logo "Hi-Res Lossless" appeared while i was listening on my Airpods Pro 2 (Lightning port). So i just wanted to know that if Apple Music has supported lossless music on Airpods yet or it's just showing the supported quality of the song, not the quality playing on my Airpods? Here are the picture attached!
