Appearance
I don't think the waveform is specific to an individual device. I have seen waveforms with the sha256sum daad0e579ab252e69633af72b2a6c57066a7501b7a32eebb43c215588d7c8e9f length 2686280 on two devices. What more probably is device-specific is some vcom setting burned into the tps65185. That could be automated during fabrication. In an older image I have also seen a waveform with the sha256sum d5038637176d76ae6842057cc187b2f5595b3625d3b011e016064d35d6f4c1e0 length 2686291. I think it is sometimes included in an update.
