I cannot rule that out although I find progressive recording more

I don't really see them, I see many artefacts.

Please lets agree on two things:
(In general) you cannot output interlaced video like it worked on
CRT TVs until (at least) the eighties. It just doesn't work, no
matter if you claim it could work for a fourth time in this thread
or not (not even with a CRT computer screen).
(Specifically for your file) you may be able to improve quality
with denoise filters (and possibly other filters) but this is in
no way related to the video being de-interlaced or not.
