900p + high AA on PS4.
540p + no AA on Switch?

Looking at the only comparison for detailed graphics in UE4 we have - Snake Pass - Switch is much more likely to be at or very very close to 720p.  I would bet on 720.  And also, tendancy seems to be to keep AA in UE4 games rather than lose it for a higher resolution.  Snake Pass has high quality AA for example.
