I love how you can pull out 100 studies and side by side comparisons of recording tools/listening devices much more precise than the human ear that all show this as being flim-flam; and still "audiophiles" will convince themselves to spend 5-25k on specialty equipment that has no effect on their experience.
You're better off spending your money on a bog standard DAC/AMP (feel free to opt for tube even, if you insist) combo running through a pair of decent headphones off of 320kbps MP3/AAC (or FLAC, if you insist) source. Even, if we took your subjective insistance that this specialty equipment improved your experience by .00001%, it's probably not worth the 500-1500% increase in expense.
As to your specific example, I can guarantee you that your Bluetooth codec (LDAC or not) introduced far more sound artifacts than the difference between 16 and 24-bit sound.
Placebo is one hell of a drug and has an effect much larger than .00001%. It might not pass an ABX test, but it absolutely does sound better to those who want it to sound better.
