There may be historic benefits to up or oversampling. Philips's original DACs were 14 bits, 4 time oversampled, which if you do the maths, gets close to 16 bit resolution. Also, when filtering was analogue, it's much easier to avoid cutting into the audio bandwidth with an oversampled signal as the sampling frequency is then four times higher.
Benefits of upsampling/upconverting? | AVS Forum

The benefits of oversampling are usually combined with a feedback loop with a filter in the forward path to create a noise-shaping delta-sigma converter. This pushes quantization noise out of the signal bandwidth, and into other (usually higher, as in a low-pass converter) frequencies.
Upsampling vs. Oversampling for Digital Audio | Audioholics

Upsampling would give us the same benefits in frequency response that we have gone over, however we can achieve the same effects by sufficiently oversampling our signal both at the DAC and ADC. Upsampling has no effect on our digital filter design problem since all our digital filters are FIR (finite impulse response) and all have linear phase.

Re: What's the benefits of DAC's audio output upsampling? Reply #3 – 2019-05-13 20:18:16 The output of the DAC must go through an analog filter, and increasing the sampling frequency makes the filter simpler and cheaper.
Upsampling? | Stereophile.com

Upsampling: Take a digital stream that is at one sample-rate and bit-depth and create more slices (higher sample-rate) at a finer bit resolution (more bits = greater bit-depth). This can happen anywhere a designer sees fit to do it. A DAC will automatically adjust to an incoming digital sample-rate/bit-depth up to its internal capability.
Upsampling - Music Servers - Audiophile Style

I also guess that the benefit of upsampling is for DAC architectures that upsample everything inside the DAC before converting to analog. And it's only a benefit to upsample from your music server, if the music server is doing it more efficiently (i.e. the DAC having to do less upsampling work results in better overall sound quality).

Does Upsampling Improve Sound Quality? - posted in Computer Audio: Can anyone please outline the potential benefits of upsampling audio files using the DSP Output options in JRiver Media Center 19? I have read opinions that indicate it is worthwhile although others maintain that it makes no audible difference. If one does upsample, should one upsample to a …
