Cropped 1080p media reports as 720p

If it's purist to say that something whose dimensions literally include 1080 is not 1080, I guess those "purists" are the kind who like to alter the aspect ratio of what they're watching to fill the screen regardless of the distortion!

Let's look at it the other way.  If I sold you a TV that had the resolution of 1480x1080 would you except that as a 1080 Full HD TV?

Of course not because it's not 1920x1080.  Same with the video to a purist.

Overloading a specific meaning onto an incomplete descriptor is what leads to this ambiguity.  But you said "1080 Full HD", not just "1080"; that TV doesn't meet the first description, sure, but it does meet the second!

Yea, talking resolution is a can of worms. Yes I snuck "FULL HD" in there on purpose. 

The other argument that's just as valid is to say anything over the HD resolution can't be 720 but the next highest common resolution or FULL HD. <-- What the server shows on detail screen as 1080 for this movie in question.  From this point of view (likely most common) the cover art plugin is wrong.

To me personally if the height or width is greater than the spec of HD/720 it must be the next higher resolution such as FULL HD/1080. To me it fits that box/bracket.

Has this answered your questions?

What were the final dimensions being used by Emby to determine resolution? I ran a blu ray rip through handbrake and auto cropping produced a resolution of 1768X800. Emby is reporting this as 720 where Plex shows it as 1080.

Either you or Handbrake picked a size of 1768 width to make the copy.  blu-ray HD is 1920 wide.  blu-ray production makes either full 1920 width or full 1080 height.  A professional blu-ray disk does not offer 1768 width x 800 height.  The copy should have been made to 1920 x 868.  It would then be labled, correctly as 1080P. If you don't reach 1920 width or 1080 height, you don't qualify to be listed as blu-ray 1080P.  This is an industry standard.  If Plex let's you do it, they are not abiding to the industry standard.

This is a lesser used Aspect Ratio Todd-AO.  There have been only about a dozen big films in the last 20 years with this ratio:  https://en.wikipedia.org/wiki/Todd-AO

Thank you. This was a handbrake setting. It’s usually good at guessing appropriate cropping, but I’ll manually overriding it this time to keep the width at 1920 and see how it looks.

We really need the thresholds list in a KB or Tutorial that can be referenced as this comes up a lot.

[Happy2Play 9780]

Another note is this will affect playback option also if not Direct Playing as these items will be limited to the lower Resolution they are identified as.

Since the number actually states the height, calling 1480x1080 anything other than 1080 is plain wrong.  In this case the vertical dimension is not cropped.  And even if you are pretending that all videos are 16:9 (really?), then 1480 horizontal is bigger than the width of a 720 video, so 720 is still inappropriate.

For videos that are vertically cropped (e.g. 1920x960), I have seen both the actual height (960) and the container height (still 1080) used, with the second being the more common.

This!

1480/1440/18whatever x 1080p is almost always the product of a Reencode with cropping enabled. I never had one file where this would be a 720p file. 
E.g. I reencoded The Whale (1920x1080 untouched, but AR 4:3 in 1080p) with cropping enabled to save a bit space, now it sits at 1440x1080. Is anybody telling me, I reencoded it to 720p like Emby tells me? Common... Not talking about the movie Jakie or several others which are cropped at 1792x1080 and also seen as 720p which is totally ridiculous.
