Haha, that is exactly the first thought I had upon seeing that image!

I think, in addition to the things you mention, there’s something about the costumes themselves that lend to the “action figure” look. It’s something that’s been bugging me about a lot of the Disney era costumes. While much better than anything in the PT, there’s something very artificial looking about a lot of the new props and costumes. It’s like the fabric is too thick, and high quality. The stitching is too good. The molded parts (helmet, armor, etc.) too cleanly molded/sculpted and too nicely painted. Even the weathering and wear-and-tear looks too curated and “artistically” applied. The costumes in the OT looked like real clothes that people actually wore and lived in. The newer stuff looks like an art department with too big a budget trying to replicate that look while using much higher quality materials.

I dunno. It’s a small nit to pick but it’s something that sticks out to me from time to time. Oddly though, on screen I feel it’s much less of an issue (not that it goes away entirely, but that it’s somewhat mitigated). It’s these production photos and behind-the-scenes things where it really stands out.
