So there is a benefit in / requirement for upsampling.
I don’t understand why it is being questioned all of a sudden?
Only when you have a really crappy DAC (filterless NOS regardless how expensive) or one that only has a poor slow reconstruction filter then you can improve signal fidelity by using upsampling (that has a good filter, there are poor filters too).
For your normal standard DAC there is no benefit.
