Posts like this is why the conversation continues. People are perfectly capable of discerning between a reflection and an actual dent in the body just as they would a real car. And our lighting of the vehicle will change throughout the day and night.
Might as well add a more lengthy commentary. And to note, I was always going to keep my Jazzinc 89 order after seeing the test batch videos but was wondering if anything could have been done to fix the mold sinks, especially near that wheel well. Joost addressed it and what his production was like and the costs involved. I'm glad he was able to fix the canopy issue and paint rub in shipping.
Now if you want to do that HT comparison, the injection mold indentations will be noticeably apparent regardless of whether it's reflective glossy paint or a more matted one. As long as there is a specular sheen from the light source lighting up that black paint surface, any indentations will show up as shadow. I actually think the glossy paint in Jazzinc helps hide the dents more since they get mixed in with real-world objects in the reflection.
With a matte look, you literally just have the light sheen of the black painted surface and the sink hole shadow showing up within the sheen. The most obvious times when the mold sinks appear egregious in the Jazzinc is when there's barely a reflection and it's just the lighting creating the white specular sheen of the black paint and the sink hole shows up within it.
Ex in matte colors with no gloss reflection.

Here's a 4k image close up of that wheel area in the HT, with lighting directly hitting it and specular sheen all over the black color. Mold Sink marks would show up easily here if they were there

There isn't much reflection going on in this shot below. Notice in green circle, those dents are no longer as apparent, there's barely any white specular sheen from the lighting there. In the red circle, they are very clearly visible when the lighting hits that area as the HT above.

HT on top vs Jazzinc on bottom. The Jazzinc mold sinks easily showing up again in the specular sheen on the side of the body. If the lighting was hitting it differently so that the whiter specular sheen wasn't there and it mostly just shows the black paint color of the car, then the mold dent won't be as noticeable.

The HT does have a mold sink here under the green arrow, it looks less egregious since it sits close and follows that gap line. Again, the noticeability of that dent drops off as the white sheen fades into the black color.

I find it to be an interesting engineering question on if there's some steps in the actual injection molding production that could be researched to lessen the effect, and save them time on the hand filling and sanding for any future vehicles.
