Here's what I'm experiencing with wp cli v2.2.0 release 4/26. upon using wp theme list, I now see an error message next to themes by Elegant: MyResume, Minimal, Glow, and BlueSky. I see this:

BlueSky | inactive | version higher than expected | 5.0.12 | network
this error message is a false positive. The Elegant theme Blue sky is on current level today, 5.0.12 and does not need updating. Yet, wp cli thinks it needs updating. It happens with 4 of the Elegant themes we have installed on multi site. Something is out of sync. Plus the legend for the new version of wp theme status does not include U -update Available.

However, regarding the legend missing the definition for U -update Available seems to be appear as expected today. It looks like it was fixed. I just ran wp theme status today and the U = Update Available now exists.
