for anyone with the same problem, I add a border until the photo is larger than 1600x2650, at which point you can see the entire photo on the screen, as shown here:

This is one of the dumbest things I deal with on the pixel, although there are a lot of dumb things with this phone.

OP below:

ever since I got the pixel, one of the most frustrating non-Functionalities has been that I have to manually screenshot any picture that I want to make into a wallpaper background because my Google pixel 6 enlarges by about 3x any photo, I choose to make my wallpaper background and cannot make the picture smaller by pinching it smaller.

but now even if I save a screenshot, it blows it up more than 3x and I have to manually add a giant border around the picture in an external app so that the picture itself is much smaller if I want to see the entire picture on my phone wallpaper.

is this just some shitty thing with my phone or do all pixels do this?
