Are there cases where a 漢字 in a given context has a different 読み just because it is spoken in a different dialect?

Question

As is well known there are many different dialects in Japan. There are many examples where the vocabulary, the grammar and/or the pronunciation are different in different dialects. It recently occurred to me that the 読み of a 漢字 may be dependent on the dialect as well.

For example, I am wondering whether 赤い is always read as あかい regardless of the dialect, even though the pronunciation of あかい may be different in different dialects. To give another example, if 日本 appears in an article, is it always read as if にほん or にっぽん had been written there, or are there any chances that it would be interpreted as something else in terms of kanas based on dialects.

To reiterate, I am not asking about the differences in pronunciations between dialects, I am asking whether the way a 漢字 is interpreted in terms of kanas (that is how 読み is usually defined) can be different in different dialects. I would also like to exclude 名乗り読み and the names of places since those are a little bit too convoluted. I am also aware that the accents may be different in different dialects (the classsical example being various 漢字 read as はし), I am interested in differences beyond the accents. I have done a little preliminary research on the topic and it seems the answer is that the 読み are always the same (I may be using the wrong keywords though), but I would like to confirm this is indeed the case.

I would really appreciate it if anyone can confirm that it is indeed the case, or if it is not, provide a non-exhaustive list of cases where the 読み are different in different dialects.

It's up to the author whether to write a certain dialectal word in kana or in kanji with furigana. For example, there are many words for snail in Japanese, most of which are typically written in kana but have also been assigned to the kanji 蝸牛 as jukujikun. You can read this page to see various furigana have been actually put on top of 蝸牛 by novelists from various parts of Japan (蝸牛【かぎゅう】, 蝸牛【かたつむり】, 蝸牛【でんでんむし】, 蝸牛【なめくずら】, 蝸牛【まいまいつぶろ】...). Therefore, it is only natural to me that different dialects can have different ways of reading a kanji word.

Now you may ask: Would an average speaker of modern standard Japanese ever intentionally change the reading of a certain kanji word because a certain dialect is being used? Aside from proper nouns, I don't think there are many such examples, but one example would be 海人; the ordinary reading of this is あま, but even Tokyoites may read it as うみんちゅ when they know the context is related to Okinawa.
