It was updated. The stripes came from Obama Admin and behind him when they had the meeting together. Search other pictures you can see the Oval Office got a makeover.

Yall keep posting this same thing, it got debooonked. Look at Dan Scavino photos you can see they changed the wallpaper a while ago (its the same as in the biden pic)

I found pics of trumps oval office with the new wallpaper. I think this is debunked now

there was a documentary on History channel a few years ago, Inside the Whitehouse, or something like that. Anyway, during the inauguration, the prior administration is moved out, and the new is moved in along with any changes to wallpaper, general decorations, etc. If he picked that, it was ready to go by the time he arrived. Trump leaving departing at 7AM probably helped expedite the transition. Think Extreme Makeover, whitehouse edition.

I also thought it looked different

Just a different angle. You can find pics of Trump sitting there with ni wallpaper.

It looks the same from this video. Maybe that picture of Trump with the stripped wallpaper is outdated because here is is in the oval office and you can see the beige wallpaper. https://youtu.be/4OHClLSwpI4?t=36

Probably just updated.
