They only care about Spatial audio, that technology requires lossless:

Spatial audio is why Apple is supporting lossless. This has nothing to do with resolution or bit depth.

See:

@wklie

Dolby Atmos music from music streaming services and audio tracks from Netflix use a lossy codec based on Dolby Digital Plus.

Dolby Atmos on UHD Blu-ray uses a lossless codec based on TrueHD.

This is made even more complicated when there are special cases like Dolby MAT for Apple TV 4K, etc.
