Haven't flown in a few years but I flew a ton 2017-2020 and airlines could never scan the barcode on an eTicket if I forgot to turn the brightness up all the way. I'm guessing it is more because of glare than contrast though if that makes you feel any better.

They are Aztec codes or PDF417 codes, and software for reading them is generally less robust and less smart because less investment has gone into clever ways to align the codes quickly. The codes themselves also have less good alignment markers, especially for dealing with lens distortion.
