Peak to peak noise can greatly depend on the sample rate and waveform update rate. i.e. all thing being equal, a faster update rate scope will appear "noisier".
This is why RMS noise is used for comparison.

Loading default ("factory") settings is the normal behavior of preset in almost all of the (probably over 100) instruments I've used in my career.

Most scopes have a dedicated Default button which is different from the user Preset function. Keysight, Tek, Lecroy, Rigol, Siglent, GW Instek all call it Default.
R&S is the standout here in calling it Preset.
Yes, the Preset button on the MXO4 is actually the Default function, I would not have guessed that without trying it. "PreSet" in english means literally as it says, "pre", i.e. you have set up the configuration before you Set the function.

Many new instruments are.
It's a very convenient feature to return your scope to your preferred setup with a single button press rather than need to recall a previously saved Setup however they can be very useful for more specific tasks in that you can save several.

In the case of the MXO4 the Preset button works as the Default button on other scopes. You can set it up in the setting to a user defined function though, but by default, it's Default function as per all other scopes.

Maybe this is the RF background of R&S leaking into the user interface. On RF equipment there is no default button but a Preset button to set the equipment to default settings.

Yes I see lots of Preset on anything RF whereas scopes all seem to use Default.
Either way, factory Default/Preset is the default option and User definable Defaults/Presets in a couple of forms available too. Some assign user settings to a Default/Preset while in older gear this could also be done as a Setup, just not as quickly/easily recalled.
