Thanks for updating us. I had been wondering about you.
I was just going to post saying don't be put off of stealth dyslexia so easily, and aeh beat me to it with much better information and more nuance! Still, I will chime in with my two cents. I was homeschooling my then seven year old son and it was just *weird* what he was doing with reading. He learned late, first of all. And then he could read James and the Giant Peach, but couldn't read the word "parties" aloud to me. There were odd inconsistencies, especially when reading longer words. BUT, when I took him to reading specialists and asked about stealth dyslexia, none of them had heard of it, and they told me he couldn't be dyslexic because he was reading too well.
I took him to Lindamood Bell, and he scored in the 90th percentiles on comprehension, but much lower on decoding, and the director of the center noted that that was odd, because most kids decode first, and then comprehend. I had read enough of the work of Brock and Fernette Eide to recognize that pattern as typical of stealth dyslexia, but the LMB people had never heard the term.
Eventually, he was diagnosed as dyslexic and dysgraphic. It took a full psycho ed eval -- several days of testing. The tests really showed that there are significant strengths -- and significant weaknesses. We paid the big bucks for two intensive weeks of remediation at LMB. It was worth it. He used to guess at longer words based upon the first and last letters. After remediation, he was decoding.
He is in middle school now. He is still slow, and has poor accuracy at times. His spelling and handwriting will never be great. But he is not being taxed by the reading demands of text books, etc. because (I believe) we remediated. He is aware of his own weaknesses and has some strategies to deal with them.
If your kid needed some help getting to be a fluent reader, I would keep alive the suspicion that there might be some dyslexia. Don't assume the "experts" know what dyslexia looks like in a gifted kid. They probably don't. Read up on the work of Brock and Fernette Eide. They have a slideshare presentation online, and lots of other resources. If what they have written sounds like it "fits" your kid, I would definitely want to follow up with a full evaluation done by someone who understands giftedness and learning disabilities.
