Are these chisels okay?

I bought the narex richter 5 piece set from tay tools a month back and never questioned why my bevels come out slightly different via honing guide. Today I decided to throw check for squareness and I’ve found the entire blade seems to be “bent”

First photo shows a hollow and the second showing a bit of a belly

The entire set has this same issue with the belly sometimes being on the right/left
