Tag result only if requested individually?

Windows 10. On a jpg from an iphone, if I use

"exiftool -s -a -u -G -File:JPEGQualityEstimate img.jpg"

it outputs the quality estimate of 95. If I use the same command without specifying the quality estimate tag, i.e.,

"exiftool -s -a -u -G img.jpg"

it doesn't show the quality estimate in the output. Is there something I'm missing? TY.

If you check the note on that tag's entry on the Extra Tags page, you'll see it says

      For performance reasons, this tag is generated only if specifically requested or the RequestAll API option is set to 3 or higher)

TY! That's the last piece of the puzzle to make exiftool work well in Directory Opus with all the desirable tags.
