I just received a call from a Dell Tech who confirmed that both the UHD panels on the 13.4" 9300 and the 7390 2-in-1 are the same, and DO NOT use PWM.

He also said that only the FHD panels use PWM.

Does disabling 4k mode on 4k screen extend battery life to match FHD version?

No. Battery life is worse on the 4K version, because 4K screens require a stronger backlight to reach the same level of brightness as FHD screens. This does not change if you lower the resolution.
