With the latest update, you can now use gyms like stops and get items. So far, every time I have done so there has always been one item that has a red background and number.
Is this a bonus item since I am part of red team? Is there any special meaning to it at all?

Based on my observations, your theory appears to be correct. Spinning a disc that is on a gym that your team controls will give you an extra item. That item will be indicated by the colored background that matches your team's color.
For reference, I am on Team Mystic. When spinning the disc at Valor and Instinct gyms, I did not receive a "special" item, but I have at the Mystic-controlled gyms I've spun.
