I would hardly consider that pricing insane. Consumer TVs are massively subsidized by the smart tech built into them, in some cases by up to 60%. Plus, they are often fragile with cheaper components because they are expected to be mounted in “safe” places away from unusual conditions or extreme temperatures.
Considering the more robust construction (for commercial use) and lack of subsidization, I would consider those prices to be spot-on and rather reasonable.
