The man-page indicates that mount expects UUIDs to be lower case.
Mention that NTFS and FAT volume IDs are to be specified in upper case.

.BR mount (8)
uses UUIDs as strings. The string representation of the UUID should be based on
lower case characters.
+But when specifying the volume ID of FAT or NTFS file systems upper case
+characters are used (e.g UUID="A40D-85E7" or UUID="61DB7756DB7779B3").
