What bluetooth codecs does my Q70A TV support?

[Deepfry_water]

I want to get a pair of wireless headphones to watch TV with but I don't want to have the bluetooth lag I'm reading about so I'm looking for a pair that has the aptX-LL codec. 
So my question is what type of bluetooth codecs does my Q70A TV support? Does it support aptX-LL codec? And maybe what type of bluetooth version does it have.

And any recommendation for a pair of bluetooth headphones that works with the TV and has no lag (sound being heard after the image or viceversa) is welcomed. 

If it helps, my TV Model Code is QE65Q70AATXXH

Hi @Deepfry_water  Your Model supports Bluetooth 4.2  https://www.samsung.com/uk/tvs/qled-tv/q70a-65-inch-qled-4k-smart-tv-qe65q70aatxxu/ , however in terms of Sound quality little discernible difference from the  latest 5.0 version.  https://audio46.com/blogs/headphones/do-bluetooth-5-headphones-sound-better-than-bluetooth-4-2 

As far as I can determine though aptX-LL would not be supported.
