No. If the price delta was (still) so high, Apple quite simply wouldn‘t release a Watch with micro LED at all. So either the rumour is wrong or your calculation of the price delta (in 2024) is wrong.
well I am more inclined that it wont be released, cheapest micro-led tv now costs 80 000$+ and cheapest oled tv like 900$, so unless Apple unveils some miracle manufacturing process that they have kept under covers for years, no micro-led AW
