Saying that AptX is lossless since 2016 is blatantly false. And yes, just like with HDMI and USB, AptX standard naming and Qualcomm feature naming schemes are a misleading mess.

There are 4 flavours of AptX (linked article states this as well), and only the latest supports lossless, but is available only on very few chipsets and devices so I even forget that it exists, because for all practical purposes it doesn't.

Denon Perl Pro, Bose earbuds and Cambridge Audio M100 are the only non-chinese earphones that I know of that support AptX lossless and the latter are not even listed by my local importer. Plus, you need a very specific (expensive) phone to use them because AptX Lossless is not available for all chipsets. Basically, Asus ROG 8 or Xiaomi Redmi K70 Pro for ones available to buy for me, and then it's not available at every retailer, either, and the b2b wholesalers I have access to through work only list ROG Phone 8 (~1200€ retail).

In conclusion, to make use of lossless AptX you have to jump through many hoops and spend a lot of money—700+€ phone and the 200+€ earphones. The standard is far from being, well, a standard; common and widespread. 99,9% of devices on sale and in use by people only support older AptX standards, mostly AptX HD (which is not lossless!).
