ok, first with your pic - the 432hz result can be achieved with any frequency. it depends on the size and volume of whatever container is holding the water.
when you listen to music, what you're hearing is a logarithmic combination of frequencies. so, a major third interval will always be the same mathematically speaking, regardless of pitch. since music is relative, all major thirds will sound the same in relation to whatever comes before it.
432 is more appealing to you for a few reasons. the first is that, it sounds 'fresh' - anyone who's played guitar will know this feeling whenever they tune their instrument differently. you're so used to 440hz that any other tunings/variations will sound new. your brain is designed to ignore repeating stimuli, so after a while of only listening to 432hz music, 420hz for example will also sound fresh, new, and different.
physically speaking - 432hz is a lower frequency, so there is more 'space' between the waveforms. it's a similar effect to why slow tempo music feels more relaxed than high tempo. it's all about spacing.
due to various resonant frequencies, harmonics, etc. you will never hear just 432hz. you can tune two pianos to 432 and they will have different tonal characteristics. the only way for pure 432hz is to only have music made via synthesis instruments. generally speaking with most wooden instruments, whatever it's tuned to will actually be the least present frequency.
what about notes? 432 and 440 only pertain to the note A. what if its a song played where no A note is present? what about different tuning systems that do not use the standard 12 note equal intervals that western systems use?
also, electronically changing from 440hz to 432hz in audacity is not the same as initially recording in that tuning system. there is a lot of electronic artifacting that happens, causing that illusion of vinyl warmth (i make music and use that as an effect by pitching down, then pitching back up for artifacts)

finally, different types of sound textures will react differently based on the tuning. you don't always need to be in tune relative to the music is playing. the beach boys did this a lot in their music, they played on the idea of resonant frequencies not being present or being over represented in a piano, for example, then recorded lines and melodies centering around that in order to give the illusion of 'new instruments'
so, say you have a piano tuned to 440. while playing, an osciloscope may register something at 1633hz, not even divisible by 440, not present in any key with an A440 present. but, they can tune a tambourine to that frequency, and add it to the mix to embellish the piano despite the fact that, from a music theory standpoint, it 'shouldn't fit'
this 432 stuff is just snake oil for the most part. i do, however, believe that droning sounds tuned to certain pitches can have an effect, as well as rooms tuned to certain frequencies (a lot of old architecture used this for healing purposes)
