There’s definitely a difference in image files name formats between movies and TV episodes; based mostly on a movie being a single entity and a tv series dozens or hundreds of separate entities grouped together.
You might have misread the published guidance (which is here; scroll down to “TV Show Artwork”).
Usage details
Episode image
seriesname/season 1/episodefilename.jpg
Season poster
seriesname/season 1-poster.jpg
All Seasons poster
seriesname/season-all-poster.jpg
Series poster (available only while using Library)
seriesname/poster.png
Series fanart
seriesname/fanart.png
Series logo

The “seriesname” followed by the slash indicates that “seriesname” is the season folder: TV Show (2023)…
And the rest (for example, “poster.jpg” or “fanart.jpg”) are files within the “seriesname” folder. Note that they do not include the seriesname or year.
Movies will include the full title and year in the image type filenames because lots of users put multiple movies all in the same folder, and this is necessary for Infuse to determine which image goes with which.
You’ll notice something similar when TV episodes are all grouped together in the same folder: the full episode name will precede the “-thumb.jpg” suffix — my original preference — but one I now see is completely unnecessary for clear reasons.
