It's simply not supported.
Deletes will reconcile wirelessly (two-way) on POP or IMAP.
Read marks will not wirelessly reconcile at all.

The read/unread is supported in IMAP. It may not show it in the matrix, but my own testing today shows that it works. I too am trying to make the decision between POP, IMAP, and Gmail App and have played with all combinations as of late.
I think the POP wins for speed of delivery. The App wins for threaded, true to gmail, feel. And IMAP wins in the fact that it does do the read flag nearly instantly.
An issue I had with POP and IMAP is that a delete really just takes the "inbox" label off of the email and it is still in "All Mail". I kind of want the delete to truly trash the email. A delete in the App does a true delete.
None of them support adding a label which is what I really want. That would be great. So right now I am using the App and have deleted the POP and IMAP versions, but I am not sold on this app. I think the message inbox is faster and easier to deal with. But the App does allow for overall searching, a real delete, and archiving (only really useful if the thread already has a label on it).
