Don't think I've ever seen this discussed before but does anyone else find that face shot we get of RDJ in the MCU films to look a little off?

I'm watching this prequel to Wandavision at the moment and I've got to say it looks wrong.

i.e. It looks like he's wearing a GIANT old style curved glass space helmet, yet when it cuts back to a full body shot its clearly a little close fitting face mask.
