Yes, that's a little more gap than typical.

Some of that gap is due to the front derailleur having to also work with larger "standard" chainrings. Not easy to do much about that. I set the front derailleur height per Shimano's service instructions, 2~3mm from the top of the tallest tooth. Service Instructions here:

The rest of that gap is unfortunately due to the front derailleur poking into the frame's slot where it mounts!

SRAM makes a little angled shim that fits between the front derailleur and frame, that tips the tail down a bit and helps improve shifting. Alas, I googled but couldn't find an image of it! My google-fu must be getting weak...

Can you ask at a bike shop if they have the SRAM angled shim? Maybe they'd special order it...

This mismatch is just one of several other factors in shifting the chain onto the frame, but doesn't hurt to address this one too!
