I wonder if the environmental costs of dyes are externalized to taxpayers and private individuals, like many other environmental costs. That reduces the incentive for the supply chain.

Imagine if the 'green' solution saved them money. Then they'd be funding R&D more avidly (some are, per the OP) and rushing to implement the cost advantage over competitors.
