There's definitely a situation in which calling is profitable here, given certain reads on the reg or if the fish is a massive station w/ TPWK/MPTK, etc.

Like say we have 2k hands on reg, and have a read/note that says consistently stacks off light in pots where he iso'd vs other regs or w/e. Thats obviously not the situation here, but its plausible given enough time vs villain and hero taking time to gain reads on regs at his stakes.
