Confusion about Chromecast Built-in firmware

[pabulous]

Hi, I'm having some issues with the Chromecast Built-in functionality on my Bravia TV.

Recent versions have had seriously out of sync audio so I had to downgrade it to the earliest version my TV came with (1.56.292394)

My confusion is that, according to this support page - https://support.google.com/chromecast/answer/7124014?hl=en#zippy=%2Ccurrent-production-firmware-vers... - the current version is also 1.56.292394. Meanwhile my TV says the current version (and the one it wants to update to) is the much later 3.72.435199.

What is going on?
