I don't really know the specifics, but relatively, I cannot tell that large of a difference (if there is a difference) between some of the shows from Crunchyroll to Blu-rays. If there is, it's not big and pretty much neglageable.
Mostly I was talking about the actual animation, but I fail to see how a TV version could be better than the original or modified Blu-ray versions.
Again, I'm not calming that they are perfect, and you seem to be the only person that has actually claimed any specific instances of this happening. I'm sure that these can be fixed and I'm sure that they have a pretty largely good with their grammar and spelling.
Typesetting is another thing that no one has explained to me, and you seem to be the only person to be able to do that. Again, I'm not claiming that they are perfect, and personally I don't really like that text you mentioned. However, I see that as a much smaller issue than something like correct spelling, grammar, and translation. If they chose to fix it, good for them, but I don't think it should be a necessary thing they should do.
