Yup. They claim 10,000 LEDs for the 12.9-inch iPad Pro. That means they're a
lot smaller than those on the 16-inch MacBook Pro, which also claims 10,000. (By my calculations, the 16-inch has 10,368 LEDs, and the 14-inch has 7,952.)
For the iPad Pro, I'm actually unsure. The MBPs have a dedicated LED row for the menu bar and separate rows for the rest; perhaps the iPad Pro does the same for the status bar. I haven't found a grid size that adds up.
Either way, they claim 10,000 for the 12.9-inch:

and the 16-inch:

but not the 14-inch:

So by the same pattern, the 11-inch would have LEDs that are slightly smaller than the 12.9-inch's, but also
fewer.
It's probably the 'smaller' part that kills it. They'd be the smallest of them all, and probably about 8,000 of them each, and maybe Apple just can't find someone who will produce enough yield at volume at that size.
