FP6 aptx Lossless?

Just got my Fairphone 6 yesterday, it’s amazing!

Apparently it has a Snapdragon 7s Gen 3 processor, which by default supports aptx Lossless, but when I connect it to my earbuds which supports aptx Lossless, there’s no option to turn this feature on, nor does it show up in developer settings… Can anybody help me to confirm?

I’m on FP6.QREL.15.91.0

I don’t know/care what codecs the processor should support. According the FAQs on Fairphone’s website it should be supported.
When having a look at the available codec in the developer options I also can’t find the codec listed there with the same naming. Eventually it’s this codec just with a different naming:

I’m on FP6.QREL.15.105.0
