I do NOT think so. Before I answer the question please take a look at these answers upvoted by musing:

These are relatively short answers that got generous upvotes. I have seen longer answers that never even got an upvote. But I can also understand why it might look like that only the longer answers are getting the higher upvotes and perhaps this is what you mean by 'emphasis'.
I would like to point out that it is not the longer answers that are getting the highest upvotes but rather the answers about which the musing curators feel that they were most relevant. In some cases longer answers also indicate that it is full of details and was produced using hard work. It goes without saying that even some of the long answers do not fulfill the criteria of a good answer as well.
Here is what musing has to say about good answers:
- What makes a good quality answer
- Good quality answers grab the attention of the reader without being spammy or click-baity
- Answer the question that has been asked. Refrain from going off on a tangent unless it provides clarity or an example supporting the answer.
- Provide insight and support to opinion based questions
- Formatting should be neat and help guide the reader through the answer
- Quality answers do not have a minimum length, but providing insight and elaboration to a “yes/no” answer can be much more helpful.
- Be original!
