Upsampling & bypass filter switch

If I have upsampling turned on but have bypass filters switch turned on - it appears that no upsampling is occurring
If that is true do I need to run dsp but in flat settings if this is possible in order to get the benefit of the up sampling ?
Typically quobuz and tidal streams are going up to 64 bit float then through dsp then back down to 32bit
