I'd say later but the pics aren't the best - could you take one of each side in good light without a flash, at an angle.
The foot rim looks too fine and clean, glaze and shape more typical of later styles.
There's something very similar here

If you look at a generic 20th century plate the lines are perfect, the footrim clean as a whistle and the glaze is thin and perfectly smooth. Hold a 19th century plate in the light and even the finest pieces there's a difference. Creamier, thicker glaze / paste that is easily discernible in good light . Difficult to replicate the paste and glazes used back then.
Also some colours just weren't available and the copies often have shades of purple on that you would not find on any genuine period piece. Figures were also painted differently.
The other pics would be great, though.
