Try MediaInfo in text mode.
For your sample it prints the following line:
Scan type: MBAFF
For progressive video it would be:
Scan type: Progressive
Pulldown or not, interlaced video in 4:2:0 subsampling is different from progressive video. Progressive material has common color info for 2x2 blocks in adjacent lines (1+2, 2+3, 4+5 etc.). Interlaced material has common color infor for lines in one field, not the whole picture (1+3, 5+7, 2+4, 6+8 etc.). You can sometimes see this effect in titles and other sharp horizontal edges, one line of the edge.
On the other side, 'mice theeth' is not going to be visible if original source was in progressive scan order. Generally you see them in interlaced material on home video because different fields are separate shots in different times (with 50fps), but if original picture was shot in one time, two fields of one frame reconstruct it without this effect.

In both cases is the film speeded-up (4%)?

It depends on what telecine operator did. Generally they are equally sped up.
Amateurs can change fps in different ways - decimate/double some frames, use sophisticated interpolation/morphying etc., but it's not common practice for broadcasts.
