It just feels like they're following Disney's terrible live-action sensibilities, where instead of researching practicalities and historical craftsmanship, they're just hiring fancy Broadway theatre costumers and everybody's running around in hyper-saturated neo-technicolor polyester and pleather "armor."
I feel really bad knocking people who are obviously dedicated to their craft but the direction of fantasy television anymore is always so derivative of whatever trended last.
Weta's peerless work set an iconic, timeless, instantly-recognizable standard. If I saw RoP without context I'd be like "Oh they remade CW's Reign or is this a GoT spin-off or a Disney thing or what...?"
