In all my years on the Internet and written forums, as well as watching British TV for 50 years, there has been no notable usage of “Blighty” that caught my attention.

If I had been aware of the usage, (other than archaic slang) I would’ve learned it sooner. But it’s notable that this Anglophile hadn’t been bothered until the Year of Our Lord and Reign of His Majesty Charles III, 2025.
