Do AI detectors perform differently on B2B vs B2C content? Seeing inconsistent results across client types

running into something that might be obvious but i want to check if others have noticed it

i manage content for clients across both B2B and B2C. when i run the same humanizer output through detectors, B2B content flags more often than B2C. my hypothesis is that formal, structured B2B writing has more in common with AI output patterns than casual consumer copy does.

is this a known thing? does anyone have data or consistent experience on this? and if it’s real, does it change your approach to humanizing B2B copy specifically?
