I will add that there has been a shift in the temperature of the light in between the 1st and the 7th image as you can see in the raw histogram, it is slight but it is there .
This has changed how the areas that are in more direct light from above show a slightly different color cast, while the areas in that are mainly being supplied light from the reflected surfaces from around the sweeter don't have this color shift. this would tell me that there is a stronger light source for the last image from directly from above is warmer.
Here I have WB for that difference and just applied a tonal adjustment to reveal the detail in the red sweater ( just quick tweaks) , one side the first image and the other the 7th image mirrored. Other than motion blur and different focus the 7th is fully recoverable with a little more wiggle room allowed in the exposure before the raw is clipped.

I feel Highlight reconstruction has done a great job considering it is guessing the tonal ranges it applies to the clipped areas (which the literature freely acknowledges).
First time I have used it - may use it more in the future when I find I have stuffed up the exposures.
Where you think you are showing chipped and what you think is clipped is not from being overexposed and blowing the red with a that exposure , where a lot of people think reds are overexposed are not found in the areas contained with in the raw files reds.
For this image I used a cc30m filter to pre WB the light so that the red channel is closer to the green channel as to where they would clip this way I can maximise the red channel information I can store in my sensor.
here is what it would look like without this prewb filter
my greens are way out in front to clip in normal daylight first.
When I have done everything to put the priority on clipping the reds it does not show up in the red that you have posted above, if you look at my first image I have clipping shown as blue patches in my first image.
That bump in my red channel in the first image is all of that data where there is the very lightest pinks around that blue.
For me this would be the perfect exposure for the raw file when shooting this flower.
