Not sure about your XPS 15 but with the latest one (9500 year 2020), Dell's S3 sleep implementation in the BIOS is broken. You wake up to a blankscreen or dell logo if you have sign of life enabled.

You can confirm this by enabling S3 with Win10 as well (by default S3 is not used on Windows).

Have you resolved the issue? I have the same laptop and experience the same issue with screen not waking up from sleep.
