I'm not sure about the monks you're referring to, but generally the Sri-lankans pronounces Pali quite accurately (compared to Thais and Burmese in general), except for a few oddities. Here are some of them that I can think of now:
* Double 'g's are pronounced as a nasal guttural sound. E.g., "maggo is pronounced as "mang-go". (Thais and Burmese don't do this.)
* The short 'a' at the end of a word is sounded as a weak "er". E.g., "kamma" as "kammer". (Thais and Burmese don't do this.)
* When it comes to chanting, many of them tend to drag to last syllable at the end of the line or sentence. (The monks of the forest tradition seem to avoid this though. Some Thais do this sometimes, esp. at the end of the chanting.)
