LDAC (Hi-Res Audio Wireless Certification) is one of the Main Reasons to buy a Sony Smartphone. I have several Sony Headphones and some of them are wireless (WH-1000XM3, WI-1000XM2) but also does my A/V Receiver support LDAC.
It bumps up the Bit-Rate from 320kbit/s to 990kbit/s and is the only Codec (beside LHDC) that supports AudioCD Quality with lossless compression.
I can use LDAC on my Linux Notebook without any issues and since Android 10, every Android Smartphone Supports LDAC due to the GPL License of the LDAC Encoder.
Everything i had to do to make it running on Linux was to install pulseaudio-modules-bt (which had libldac as an dependency) and thats it. Now i can play music using LDAC on all my devices.
So it shouldn’t be that complicated to implement that in SFOS, or?
