If PsF is indicated, then the baseband test would be expected to report progressive, despite the interlaced structure, so an error should not be reported in this case.
Note that systems should be aware of the metadata flag MBAFF in AVC compressed video which gives interlaced output in baseband.
Some material will be mixed, and it would be very useful to log changes within files.
Also note that interlaced material with no movement is indistinguishable from PsF.
