Hi rom,
I have been in the same little situation, there is like two pages that i struggle see in the Ishihara book. I got my medical in my home country by a lantern test too.
What do I do when doing medical in foreign countries? Learn those pages
Not to sure what the UAE does but were I am they didn't even test my eyes!! But I prepared just in case they showed me that book!
Sorry I cant help you but there are plenty of pilots out there with very minor color perception than you think, but get a copy of the Ishihara book, makes life a bit easier
