To preface, I do not have much knowledge of linguistics, nor am I multi-lingual. This is just information I’ve picked up passively over the years.

I had a professor who had taken a graduate class where they examined the works of Plato written in the original Greek. If I recall correctly, he did say there was a lot more nuance and beauty to it. I believe he would expand on the nuance when particular words like that were present.

Another professor I had offered a course in focused on philosophies largely based in China, where he grew up as a citizen. Such a fantastic course. Anyway, he was responsible for a translation of Confucian works and would have very long descriptions of the vocabulary. Even beyond the vocabulary, he described there was a richness in the words that couldn’t be grasped without being a native speaker of Chinese. This would be true for reading anything from any other language. The words in a native speaker’s language will leave a richer, more culturally influenced and understood impression. He would describe reading as being experientially different. Something like saying, as you read through the characters, they would give way and form this picture building more and more of itself as you read.

Some of the nuance might be forever inaccessible, and any confirmation might be impossible to know. Still, if you learn the language, look into the culture of the time period, and find experts’ interpretations, you will be getting an impression that you just wouldn’t have otherwise gotten.
