Not necessarily spatial only; deinterlacing can use temporal algorithms (e.g. QTGMC does)

Interlaced content means each field represents a different moment in time. 59.94 different moments in time represented

The problem is you're mixing up Inverse telecine or pulldown removal with Deinterlacing. These are different things. IVTC is NOT a form of deinterlacing as you said, because it's used when underlying content is progressive.

So if you want to use your own definition, you are wrong ("Deinterlacing is literally any process that converts interlaced content into progressive content")

Since >90% of this is progressive content, you should not deinterlace as you suggested
