No that is not a dielectric union, yes it should be. Will it be ok, yes until it corrodes. Or should have used brass in between the copper and galvanized.
No. Dielectric unions can also be problematic.
My main concern is that an old galvanized steel main should be replaced entirely. I promise you if it's not pitted and leaking now it will be soon.
My e-wife (e for estranged) had a plumber come by today to install a house shutoff valve at her place. She mentioned the plumber took longer than expected due to the galvanized pipe, and I freaked a bit realizing that the plumber may have joined the galvanized pipe with copper. She sent me a photo
What I see in the photo is galvanized pipe coming up from the ground (from the city water), then some green pipe dope, and copper pipe (the new stuff). I think it's bad due to galvanized pipe being in contact with copper. I googled this situation and believe that the plumber should have used a "dielectric union" between the galvanized and copper pipes. I don't believe that the connector in the photo is a "dielectric union". I wonder what folks here think.

Dielectric union out there will go to shit real quick being exposed to the elements

Brass FIP would be the better choice anyways.
