I tried grayscale for a few months but it changed absolutely nothing. Videos are just as good as it turns out. I would give a try to an e-ink based smartphone if there was a good one. The only reason I got a smartphone in the first place in 2020 was access to maps/taxi/banking apps which would work with any display. But given the grayscale experience I wonder if you get used to laggy e-ink videos as well.
