I agree with Zdzichon on this. Plus, I have a Samsung phone (S23U) and the Bathys. I have SoundPeats Opera5 which supports LDAC. I also have the FiiO BTR5 that does LDAC too that I have used with the Stellia. I can confirm Samsung does support AptX. It would have been nice to include the AptX Adaptive, HD, or lossless. It still works well nonetheless.
Before you can get into the issue where the lack of support of the various codecs, it's going to depend on your source material. If you're listening to something like YouTube Music or Spotify, probably not a significant issue. Will it sound good, sure. Will it sound the best, it depends on what you're comparing it to. If you're playing FLAC files or so other lossless formats, then you may notice a difference. If you're going that, Bluetooth is getting better, but not as good a using a USB or some other cord connection
On a side note, I personally would not choose a phone based on what Bluetooth codecs it supports. I would still consider it, but it would be significantly lower. I would have my primary factors be screen, battery, CPU, RAM, and storage--internal and possible SD card support). I do like DEX and the video output support is also things to consider. These phones are nothing more than pocket-sized PCs that can do phone calls. Thus, these are a bit more about convenience than trying to be an audiophile experience.
