Dotz Revvo bed: really available?

Hello, I had contact with my current Rial M10 rims once again, this time even with rough scratches on a double spoke. Due to the convex construction of most rims, the spokes are slightly in front of the rim horn and are therefore at risk. Now the rial looks really bad, repair costs as much as a new rim. I have therefore searched for concave rims and found the Dotz Revvo. On all product photos the spokes seem to lie further inside, a boron dstein-Kontakt would therefore only hit the rim horn. But now I also know that the distance spokes – rim horn of course also depends on the dimension of the rims. So now my request to all who drive a Dotz Revvo or have someone in the familiar circle with this rim: Do the spokes actually lie deeper than the rim horn, if yes, how much? I would need this assessment for a rim with 17×7.5 or 18×8 inches, as I will decide between these sizes. kk in advance for your answers!
