Bluetooth codec support on the Poco X7

I have a Poco X7, and I can't figure out which Bluetooth codecs it supports. I want to buy headphones that use LHDC as a high-definition codec, and to be sure they're compatible with my phone, I need to know if it supports this codec. There's conflicting information about LHDC support on the Poco X7. Some sources say it's supported, while others say it isn't.

By the way, I know you can go to Settings and look at the list of codecs next to "Bluetooth Audio Codec" in the "Developer options" section, but it seems the codecs listed there aren't accurate. My Poco X7 lists codecs from the AptX family, but as far as I know, they're not supported by any phone with a Mediatek processor.

Thanks for your help!
