The bottom one stock is 13t as opposed to 11t from the hope/standard 105/ultegra/DA

The stamping on the mech says Rd-rx812. Googling that part number shows examples with 2x 11t jockey wheels and some with 1x 11t and 1x 13t as you suggest. Mine was definitely supplied with 2x 11t from new and works perfectly with the hope replacements.

Interesting.

From Shimano website, it seems the 812 has 2x11 jockey wheels, while the 810 has 11/13 jockey wheels. Pretty sure it would work with 2x11 as well.

Sorry for storming the thread, GLWS
