Sounds nice! Unfortunately the XPS13 9315 I have (similar to the XPS13 Plus you have) doesn't have webcam support out of the box and has graphical driver glitches (both apparently due to missing driver support from Intel). The OEM 20.04 image does supposedly include these, but if you reinstall you're out of luck it seems.
If you reinstall stock ubuntu you might be out of luck. You can do a preinstalled image backup and reinstall from that if needed, that preserves the drivers and tweaks from the oem image.
