I would say yes. My horse is medium brown and the sun brings out his dapples, but if your mare had dapples with that amount of turnout (depending on time of day), my guess is that she just lightened up enough for them to "disappear" or seem less visible.
Dapples are also affected by time of year and status of the coat. I have a couple that are dappled in the winter, and some that are dappled in the summer with their lightest/shortest coat.
In fact, is dappling really a color change? I'm not talking about a dappled grey, I *think* that's a different thing entirely. Dappling in a solid brown (bay or chestnut) coat is hair length and direction more than color. I think. Oh I hope someone actually knows this, now I'm curious!

Did you know that if you say the word "GULLIBLE" really softly, it sounds like "ORANGES"?
No, that's sooty factor. Heavy sootiness like the horse in your link will cause beautiful dappling like that. She's gorgeous by the way
My bay and blacks dapple right when they first shed out in the spring and fade within a few weeks. They are all out 24/7. If my black horses fade those dapples out, I sure don't see evidence of it until well into the summer (redness of coat, etc). My black mare was heavily dappled a week ago. Now, not so much. Happens that way every year with mine. As far as the poster that said hair length and direction, the hair growth direction doesn't change. You may occasionally have hair length difference but only as the horse sheds out. My black mare has reverse dappling when she's in the middle of shedding. Once shed out she has normal dappling and the coat is the same length (appears so to me anyway). I've always felt it was a difference in temperature (warmer within the center of those dapples) or oil content that causes 'health' dappling.
My two dark bays only have dapples for a month or two after they shed out - they're usually gone by July. If I get lucky I get to keep them until August, but by then they are usually too bleached. I try to keep them fly-sheeted to help the fading, but they don't get them all the time and do get that bleached look. At which point the dapples are no longer visible, despite their coats being incredibly healthy and shiny. They're only out about 16 hrs of the day.
The book "Horse Color Explained" by Jeanette Gower explains sooty as....
" a modifying gene Sty which causes sootiness, an admixture of black/liver brown hairs throughout including the tail. Due to seasonal conditions these can appear as dapples or change the horse to a 'false' liver."
It affects all kinds of coat colors just so that we can be a little more confused
We were always taught growing up that all horses can Dapple with proper nutrition and LOTS of grooming.
After feeding this morning, every horse in the barn has dappling to some degree.
Although I'm not on 24/7 turnout.
Gremmel and Zublin's research did reveal some interesting things about dappling. Dapples seem to be centers of networks of capillary arteries. The degree of pigmentation depends on the blood supply, but there is no connection with layers of fat under the skin. The skin under a dapple appears less pigmented than the surrounding areas. The hairs in the center of the dapples are shorter than those on the outside hairs surrounding the dapple. This slight difference in texture is why you can see dapples on a black horse if he is angled in the light just right
i saw your pics of your beauties.. extremely healthy and happy..
i did want to post a caution to you and i just recently learned this myself.. the tires that are used for feeders can cause abcesses, ulcers, colic and death.. the reason being is the tires can shred and pieces of the tire can be consumed by a horse, where it can sit in the stomach or intestine and grow bigger through calcification..
thought i would bring that to your attention, please hope you dont mind...
